Although ankle sprains may not be as serious as a broken ankle, they should be given immediate attention and care. An ankle sprain can lead to a significant amount of pain, as well as limited mobility. They are often characterized by the swelling and discoloration of the skin. This occurs when the ligaments are stretched beyond their limits.
The simple act of walking can sometimes cause a sprain, which makes ankle sprains a very common injury that can happen to anyone. They occur when the ankle twists in an awkward way or rolls over itself, causing a pop or snap in the tendons around the ankle. Some people are more at risk than others. These include athletes who continually push their bodies to the limits and also people who have previously suffered accidents to the feet, ankles, or lower legs.
Most of the time, an ankle sprain is not severe enough for hospital attention. There are many at-home treatment options available, including propping the leg up above your head to reduce blood flow and inflammation, applying ice packs to the affected area as needed, taking over-the-counter pain relievers and anti-inflammatory medication, using an ACE bandage to wrap and support the injured ankle, and most importantly, remaining off your feet until the ankle has fully healed.
Despite this, an ankle sprain can turn into a severe injury that might require hospitalization. If the ankle ligaments or muscles are damaged from a tear or rip, that is one sign that the sprain is severe enough for hospital attention and possibly for surgery. Even after the surgery, the recovery process can be long. You may need to have rehabilitation sessions administered by your podiatrist to get your ankle back to full health.
The severity of your sprain might become apparent if you are unable to stand or walk, consistent pain occurs over a prolonged period of time, swelling is much more severe than initially present, or if you start to experience tingling or numbness. These signs may indicate that your ankle sprain might actually be a broken ankle, an injury that requires immediate medical attention.
Although they are not completely avoidable, ankle sprains can be curbed with some preventative treatment measures. These include wearing appropriate-fitting shoes that not only provide a comfortable fit, but also ankle support. It is also recommended to stretch before doing any kind of physical activity, as this will help lower your body’s chance for an injury.
The Achilles tendon is the largest tendon in the body; it is a tough band of fibrous tissue that stretches from the bones of the heel to the calf muscles. This tendon is what allows us to stand on our toes while running, walking, or jumping, it is common for this tendon to become injured. In severe cases, the Achilles tendon may become partially torn or completely ruptured. However, this tendon is susceptible to injury because of its limited blood supply and the high level of tension it endures.
The people who are more likely to suffer from Achilles tendon injuries are athletes who partake in activities that require them to speed up, slow down, or pivot. Consequently, athletes who engage in running, gymnastics, dance, football, baseball, basketball, or tennis are more likely to suffer from Achilles tendon injuries. Additionally, there are other factors that may make you more prone to this injury. People who wear high heels, have flat feet, tight leg muscles or tendons, or take medicines called glucocorticoids are more likely to have Achilles tendon injuries.
A common symptom of an Achilles tendon injury is pain above the heel that is felt when you stand on your toes. However, if the tendon is ruptured, the pain will be severe, and the area may become swollen and stiff. Other symptoms may be reduced strength in the lower ankle or leg area, and reduced range of motion in the ankle. When the Achilles tendon tears, there is usually a popping sound that occurs along with it. People who have acute tears or ruptures may find walking and standing to be difficult.
If you suspect you have injured your Achilles tendon, you should see your podiatrist to have a physical examination. Your podiatrist will likely conduct a series of tests to diagnose your injury including a “calf-squeeze” test. Calf squeeze tests are performed by first squeezing the calf muscle on the healthy leg. This will pull on the tendon and consequently cause the foot to move. Afterward, the same test will be performed on the injured leg. If the tendon is torn, the foot won’t move because the calf muscle won’t be connected to the foot.
Flip flops are often a popular choice of footwear for many people. Flip flops allow your feet to breathe and give your toes the freedom of movement. They are easy to slip on and can be worn with virtually any style of clothing. Flip flops, however, despite their many benefits, can be detrimental for your foot health.
Despite their comfortableness, frequently wearing flip flops can create problems in the lower body over time. Issues mainly stem from the fact that people walk differently in flip flops compared to other footwear, such as sneakers. This is due to a change in one’s natural gait, which therefore creates stress in different parts of the body while hindering the body’s natural posture. Problems can also arise in the arches and balls of the feet. Flip flops provide little to no support to these areas.
Aside from long-term problems, flip-fops can also create short-term issues as well, such as ankle sprains and blisters. Weak materials that are flexible and bendable are generally used to manufacture flip flops. These materials make its wearers prone to both tripping and injuring their ankles. Flip flops can create blisters as the material rubs against the foot. People are much more at risk for infection while wearing flip flops due to their openness. This also makes it easier to scrape and cut the foot since there is a lack of protection. If these cuts are left untreated and uncovered, the risk then becomes greater.
To prevent the aforementioned occurrences, purchase a pair of flip flops that offer significant protection. The soles of the flip flops should not be floppy, but sturdy and firm, and should not significantly bend or wiggle when lifted from the floor. Flip flops made of high-quality materials will not be affected by this problem. While higher quality flip flops may be more expensive, they will last longer and provide better protection compared to a cheaper pair. Brand name flip flops sold from a quality manufacturer are a dependable option.
There is no problem in wearing your favorite pair of flip flops so as long as you do not wear them daily or for extended periods of time. Flip flops should be replaced every 3-4 months to ensure that they provide your feet with the best protection.
Elderly Americans are very susceptible to falls as they get older. Everyone experiences decreases in flexibility, balance, strength, and the senses as they age. This correlates to some eye-opening statistics. 1 in 4 Americans aged 65 and older fall each year. An elderly American is being treated for a fall in an emergency room every 11 seconds, and every 19 minutes, an older person dies from falling. In light of these striking statistics, one can see the importance of taking steps to prevent falls.
Finding an exercise program for the elderly is an excellent way to reduce the likelihood of falls. Look for an exercise program that improves strength and balance. Elderly people who live a more sedentary lifestyle, with little physical activity, are at an increased risk of falling. Wearing well-fitted footwear that provides good foot support and cushion will help prevent falls from poorly fitted shoes. Talking to a podiatrist about your susceptibility to falls and about inspecting your prescriptions will help to avoid any medication that could make falls more likely. Due to a decline in the senses among the elderly, having your eyes and hearing checked is recommended.
Around half of all falls occur in the household. Removing tripping hazards in the home and making it more accommodating to older persons can significantly reduce falls. Some notable household changes include increasing lighting around the house, installing grab bars in the shower and bathroom, and making sure the floor is clear of clutter. Other smart options include installing a shower chair, using rubber-bottomed rugs, and placing railings on both sides of stairwells.
Finally, discuss with a doctor and your family about your fear of falling. This will help to increase awareness among the population on the need for fall prevention. A lack of awareness on the matter, and a downplaying of importance are what increase the risks of falling. Following these tips can help to reduce the risk for yourself and your loved ones.
In most cases, foot surgery is often chosen as the last available option for conditions that have otherwise been unsuccessfully treated. Surgery may be necessary for several reasons, including the removal of foot deformities (e.g. bone spurs or bunions), arthritis problems, reconstruction due to injury, and congenital malformations (e.g. club foot or flat feet). Regardless of one’s age, foot surgery may be the only successful option for treatment for certain conditions.
The type of surgery one undergoes depends on the type of foot condition the patient has. For the removal of a bunion growth, a bunionectomy is necessary. If the bones in the feet need to be realigned or fused together, a surgical fusion of the foot is needed. For pain or nerve issues, a patient may require surgery in which the tissues surrounding the painful nerve are removed. Initially, less invasive treatments are generally attempted; surgery is often the last measure taken if other treatments are unsuccessful.
While in many cases surgery is often deemed as the final resort, choosing surgery comes with certain benefits. The associated pain experienced in relation to the particular condition is often relieved with surgery, allowing patients to quickly resume daily activities. The greatest benefit, however, is that surgery generally eliminates the problem immediately.
Podiatry history has shown that foot treatments continue to evolve over time. In the field of foot surgery, endoscopic surgery is just one of the many advanced forms of surgery. As technology vastly improves so too will the various techniques in foot surgery, which already require smaller and smaller incisions with the use of better and more efficient tools. Thanks to such innovations, surgery is no longer as invasive as it was in the past, allowing for faster and easier recoveries.
Over half of all runners encounter at least one injury per year. The reason for this is because many runners do not train properly. Injuries are almost inevitable due to the physical stress that running causes. While our bodies are great at adapting to the stress, it can only handle it in small doses. Injuries occur when the stress is applied too quickly for the body to handle, causing something within it to break down. With each step you take, your leg is absorbing two or three times your body’s weight.
Some of the most popular running injuries are shin splints, plantar fasciitis, Achilles tendinitis, and stress fractures. Shin splints cause pain along the inside or outside of the shins, and this pain is usually felt at the beginning of a run. The condition itself is defined as an inflammation of the muscles or tendons located around the shinbone. To treat shin splints, it is advised that you ice the shin area and stretch the calf muscles. To prevent this injury, you should slowly increase the distance you plan on running, instead of jumping into a more strenuous routine.
Achilles tendinitis is another common injury and it feels like pain along the back of the leg, toward the heel. This condition is defined as an inflammation of the Achilles which is the largest tendon in the body. The Achilles is responsible for connecting your calf muscles to the heel bone and it is caused by tight calf muscles. If you want to treat this injury, you should take a break from running to cross train with a low-impact activity.
There are a lot of common mistakes runners make that are causing them to experience injury. One mistake is stretching too much prior to warming up. If you plan to go on a run, you should warm up with a gentle 3-5-minute walk followed by a 5-minute run-walk. Another common mistake is jumping into a routine too quickly. Consequently, you should incorporate cross-training into your routine. If you are looking to get active, you should slowly weave running into an activity you are currently participating in. For example, you can try bike riding for 40 minutes followed by a 10-minute run.
Another way to prevent running injuries is to choose shoes that are appropriate for running. There are certain things you should look for when buying a new pair of running shoes. An important factor in these sneakers is flexibility. Running shoes should be capable of bending and flexing at the forefoot. However, you should not be able to bend the entire shoe in half with ease because this is a sign that the shoe does not have enough structure. Additionally, you should look for the fit of the running shoes you want to purchase. It is best to visit a specialty running shoe store to have your feet properly sized. Choosing shoes that fit properly can prevent many foot ailments.
If you are suffering from any pain from running injuries, you should make an appointment with your podiatrist to discover the underlying cause of your pain. He or she will be able to help treat your condition in the best way possible.
Our feet are important in our everyday lives. The problem is that we tend to neglect them. When this becomes a habit, it can cause significant trouble. Ignoring foot problems can mean pain, limited mobility, and expensive doctor's visits. On the other hand, if feet are cared for and looked after regularly, they will perform without pain or complication.
Routine hygiene is the most basic way to care for the feet. Wash and dry them thoroughly daily. Remember to get between the toes and keep the toenails trimmed and short. If the feet feel dry or there are signs of dryness or cracking, use a moisturizer designed for the feet.
When using moisturizer on the feet, try to avoid applying between the toes. If cream or lotion sits too long, they can cause fungal and bacterial growth. When moisturizer is used between the toes, it can also cause the skin to soften too much.
Shoes are also an important aspect of foot care. When one is picking out shoes, make sure they are the correct size. Shoes need to be snug, but not too tight. On the other hand, if shoes are too loose they can cause foot problems as well. It is highly recommended that shopping for new shoes be done later in the day. The reason for this is that the feet will have settled and swelled to their full size by then. To keep your feet at their most healthy, avoid wearing high heels or flip flops too often. Instead, choose shoes that are good for your feet. Good shoes pad the soles of your feet and support the arches and ankles.
Socks should also be worn daily with closed-toe shoes. They may feel hot during the summer months, but they absorb sweat and moisture off the feet. Without socks, the build-up of sweat in a closed-toe shoe can cause fungal problems and athlete's foot.
The best thing to remember in every day foot care is that shoes do make a difference. If you spend a lot of time on your feet, make sure that your shoes show no signs of wear. Shoes should offer ample support for the arches and the overall foot. Additionally, try to make foot cleaning and maintenance a daily habit. If you keep these things in mind, your feet will stay healthy and safe.
While proper foot care is important for everybody, senior citizens have the tendency to be more susceptible to certain foot conditions. The elderly should therefore be well informed about any problems that may arise and about what they can do to properly avoid or treat them.
Some of the most common foot problems seniors are susceptible to include foot ulcers, ingrown toenails, fallen arches, and fungal nails. A foot ulcer is an open sore on the foot and can be a result of diabetes and decreased sensation in the feet. An ingrown toenail is defined as when the nail grows into the side of the toe. Fallen arches are indicated by the instep of the foot collapsing. A fungal nails is a condition that results in deformed and discolored toenails.
In order to avoid these conditions it is recommended that the feet be inspected by the patient on a regular basis. If these inspections are carried out routinely, there is a good likelihood that problems can be identified before they become severe, or can even be avoided altogether. If any abnormality is discovered, it is important that the individual consult a podiatrist for diagnosis and information on treatment options.
Proper foot hygiene is also important. Making sure that you always have clean, dry socks on can be a major deterrent to many different problems including bacterial infections, foot odor, and certain types of fungus. Wet feet are a major cause of many of these problems. If your socks get wet, it is important to change them. Walking around in wet socks may not only lead to various infections, but can irritate the skin and result in a number of various complications. Clean, dry feet are less likely to be affected by fungal and other infections.
As people age, the fat present on your feet begins to deteriorate. The protective nature of this fat keeps the feet healthy by providing a barrier between your bones and the ground. This also aids in giving the skin on the feet a certain amount of elasticity. This is one factor that causes elderly people to develop some serious foot issues. Foot moisturizers can be helpful to avoid certain problems associated with this. However, water-based moisturizers do not work as well for elderly people as they do for the young. Instead, it is more effective to use an emollient instead. An emollient is effective because it binds the water in the foot, keeping it from becoming absorbed too readily which will result in dry skin. Emollients also have a special property called occlusion, which provides a layer of oil on the skin. This layer prevents the foot from drying up and can be very effective in treating dry skin disorders. If you can keep the skin on your feet healthy, this will substantially reduce the number of foot problems you will encounter in old age.
Proper footwear is another way to keep feet healthy. Shoes that fit well and provide proper support help prevent ingrown toenails and fallen arches.
Certain medical conditions such as diabetes or poor blood circulation increase the risk for foot issues. For individuals with any of these conditions it is extremely important to conduct regular foot inspections to make sure that there are no sores or infections present.
Poor blood circulation in the feet and legs is often caused by peripheral artery disease (PAD), which is usually the result of a buildup of plaque in the arteries. Plaque buildup, or atherosclerosis, can be the result of excess calcium and cholesterol in the bloodstream. This restricts how much blood can flow through arteries. Reduced blood flow to a certain area of the body severely limits the amount of oxygen and nutrients that part of the body receives. This leads to degeneration in the muscles and other tissues. Sometimes, poor blood circulation in the feet and legs can be caused by other conditions, such as the damaging or inflammation of blood vessels, known as vasculitis.
The lack of oxygen and nutrients caused by poor blood circulation can restrict muscle growth and development, as well as cause muscle pain and cramps, weakness, and stiffness. Other common symptoms include numbness in the legs and feet, skin discoloration in the affected limbs, slower nail and hair growth, and erectile dysfunction in men. In more severe cases of PAD, pain can be present even when a person isn't exercising, and may range from mildly uncomfortable to completely debilitating.
Poor blood circulation in the feet and legs is more common in those who are overweight or obese, have diabetes, high blood pressure, high cholesterol, who smoke, or who have a family history of PAD or related conditions such as a heart attack, stroke, etc. Diabetes and smoking place a person at greatest risk for developing poor blood circulation, although advanced age, over 50, can also increase risk.
If you are experiencing poor blood circulation in the feet and legs caused by PAD, it is important to make changes to your lifestyle in order to reduce your risk of experiencing a heart attack or stroke caused by this condition. If you smoke, quit completely. This will increase the amount of oxygen in your bloodstream. Exercising and reducing the saturated fats in your diet. Saturated fats come from fatty meats, fried foods, whole milk, etc., can make a difference in improving blood circulation in feet. It is also important to avoid developing influenza and to carefully control your blood sugar if you have diabetes.
Your doctor may recommend combining lifestyle changes with a prescription medication regimen to improve blood circulation. The most commonly-used medications for PAD are called statins and work by blocking the amount of enzymes in your body that produce cholesterol. They are known by the brand names Zocor, Lipitor, Crestor, and others.
Debilitating foot pain is a problem for many people. But just as stretching the torso can help alleviate back pain, stretching the feet can also help mend existing foot problems and prevent future ones.
The feet, as the body’s foundation, carry the body’s entire weight and can get easily strained from overexertion. Persistent sharp pain and cramping in the feet are often common concerns. Foot pain and foot problems can be due to any number of causes, and in many cases pain may be eased without medication or doctor visits. It is always a good idea, however, to first rule out any serious medical issues with a physician.
Stretching can help relax the feet and alleviate pain, but is especially important before heavy aerobic exercise. Stretching before such activities can help you avoid experiencing painful cramps or strained foot muscles. Stretches should be performed slowly and deliberately without forceful pulling. The stretch should be held for several seconds before relaxing.
A great way to stretch out and loosen up the foot muscles while sitting is to cross one leg over the other and pull the toes carefully back without overextending. Start by resting the left ankle on the right knee. With the left hand, gently flex the left foot by pulling back on the toes. Do not pull too hard; just hard enough to feel the stretch in the arch of the foot. Then point the toes of the left foot as far as you can. Rotate the motion of pointing with pulling back on the toes. This should relax and stretch the muscles on the bottom and the top of the foot. Doing this stretch ten to twenty times should bring relief. Repeat the whole process for the other foot by resting the right ankle on the left knee.
A stretch that focuses on the often injured Achilles tendon involves standing and facing a wall with your arms out and hands flat against the wall. Step back with one foot, keeping it flat against the floor. Move the other leg forward and lean toward the wall. You should feel a stretch through the back of your leg and your Achilles tendon, but do not push yourself too much. Stop when you feel a stretching sensation, and hold for 30 seconds. Ten repetitions may be done for each foot.
Stretching the feet is important for athletes or those performing aerobic exercise, but it can also help anyone with foot pain caused by poor footwear, plantar fasciitis, or long hours standing and walking. Individuals who tend to their feet by regularly stretching every day should be able to minimize foot pain and prevent new problems from arising.
Being a parent involves caring for your child in every way you can. You make sure they are eating the right food, being nice to others, and staying out of any trouble. However, it is also important that you are watchful of their health, more specifically their foot health. Maintaining good foot health in childhood is important in preventing later conditions in life from happening. As children continue to develop, their feet require different techniques of care. Here are some various ways in which you can help your child’s feet stay healthy.
A baby needs a lot of care and attention overall, but the importance of their feet should never be forgotten. Before a baby turns one, their feet change and develop greatly. It is important that during this time, a mother avoids putting tight socks on their child. She should also encourage movement of their feet so the baby can begin to feel more comfortable using them.
As a baby enters the toddler years of his or her life, they are begin to walk around. When your baby begins to take those first steps, it is crucial that they are wearing protective shoes on their feet. As a mother that is observant of your child’s feet, you may notice changes in them. This is completely normal as the feet are becoming susceptible to the activity of walking. It is normal for a toddler to be a bit unsteady or to “walk funny” at first.
When your child grows out of their toddler years, it is important that you begin to show him or her how to care for their feet on their own. Practice with your child proper hygiene in order to prevent foot fungus or infection. Since children are constantly on the move, it is crucial to be cautious of any accidents or injuries that might occur. If an injury occurs, it is advised that you take your child to be examined by a doctor immediately. Since your child is still growing, particular injuries can shift the way in which a bone or other important part of the foot is developing.
Babies and kids are always changing and growing. Your job as a parent is to make sure they stay healthy and making sure they are properly maintained. This involves proper foot care and making sure the feet stay healthy. Following this guide, your child can live a long and happy life.
Plantar warts are warts that are only found on the feet, hence the term “plantar”, which means “relating to the foot.” They are caused by the human papillomavirus, or HPV, and occur when this virus gets into open wounds on the feet. The warts themselves are hard bumps on the foot. They are easily recognizable, mostly found on the heels or ball of the foot. Plantar warts are non-malignant, but they can cause some pain, discomfort, and are often unsightly. Removing them is a common step toward treating them.
Plantar warts can cause some pain while standing, sometimes felt as tenderness on the sole of your foot. Unless the wart has grown into the foot behind a callus, you will be able to see the fleshy wart. A podiatrist should only be consulted if there is an excessive amount of pain. Plantar warts are not cancerous or dangerous, but they can affect your walking and continually reappear. Anyone who suffers from diabetes or a compromised immune system disease should seek out care immediately.
Podiatrists are easily able to diagnose plantar warts. They usually scrape off a tiny bit of the rough skin to make tiny blood clots visible and examine the inside of warts. However, a biopsy can be done if the doctor is not able to diagnose them from simply looking at them. Although plantar warts usually do not require an excessive amount of treatment, there are ways to go about removing them. A common method is to freeze them off using liquid nitrogen, removing them using an electrical tool, or burning them off via laser treatment. For a less invasive treatment option, topical creams can be used through a doctor’s prescription. This treatment method takes more time, however. Keep the wart covered for protection in between daily treatments.
The best way to avoid developing plantar warts is to avoid walking barefoot in public places. Avoid this especially if you have open sores or cuts on your feet. It is also important to avoid direct contact with warts in general, as they are highly contagious.
Biomechanics and its related study deal with the forces that act against the body and affect things like our movement. In podiatry, biomechanics are studied to determine the movement of the ankle, toes, and the foot, as well as the forces that impact them. Podiatrists who train in this specialty are able to effectively diagnose and treat conditions that affect people’s everyday movement.
Regardless of your lifestyle, age, or any other factors, many people experience foot problems throughout their lives. Twists and turns, improper balance, and added weight are just a few of the things that can add stress to the feet. These issues can also limit our bodies’ mobility that we often take for granted. Pain in the feet and ankles can also trickle up towards the lower legs, knees, hip, and even back area. This affects the way you move around on a daily basis.

The history of studying biomechanics dates back to ancient Egypt at around 3000 B.C., where evidence of professional foot care has been recorded. Throughout the centuries, advances in technology, science, and an understanding of the human body led to more accurate diagnosis of conditions such as corns for example. In 1974, biomechanics garnered a large audience when Merton Root founded Root Lab to make custom orthotics. He proposed that corrections of certain conditions could be implemented to gain strength and coordination in the area. Due to his research, we still use his basic principle of foot orthotics to this day.
As technology has improved, so have the therapeutic processes that allow us to correct deficiencies in our natural biomechanics. Computers can now provide accurate readings of the forces, movements, and patterns of the foot and lower leg. Critical treatment options can be provided to patients now who suffer from problems that cause their biomechanics to not function naturally. The best results are now possible thanks to 3D modeling and computing technologies that can take readings and also map out what treatment will do to the affected areas.
These advanced corrective methods were able to come to light thanks to an increase in both the technologies surrounding biomechanics and also the knowledge of how they work naturally. For example, shoe orthotics are able to treat walking inabilities by realigning the posture deviations in patients caused by hip or back problems. Understanding foot biomechanics can help improve movement and eliminate pain, stopping further stress to the foot. Speak with your podiatrist if you have any of these problems.
Orthotics are shoe inserts that are meant to correct an irregular walking gait or provide cushioning to the feet. Orthotics come in a variety of different models and sizes, including over-the-counter and customizable variants. Customizable orthotics can be shaped and contoured to fit inside a specific shoe and are typically prescribed through a podiatrist who specializes in customized footwear and orthotics design and management.
Orthotics are beneficial because they can help prevent injuries from occurring and provide cushioning to keep pain levels down to a minimum. They also allow for the correct positioning of the feet. Orthotics can act as shock absorbers to help remove pressure from the foot and ankle. Therefore, orthotics can make bodily movements, such as walking and running, become more comfortable as well as help prevent the development of certain foot conditions.
Orthotics alleviate pain and make the foot more comfortable by slightly altering the angle at which the foot strikes the ground surface, therefore controlling the movement of the foot and ankle. Orthotics come in different variants and can be made of various materials. To determine what type of orthotic is most suited to your feet and your needs, it is best to consult your podiatrist. He or she will be able to recommend a type of orthotic that can help improve your foot function or prescribe a custom orthotic to best fit your feet.
