Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.
The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.
The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.
If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.
Have you ever gotten up from a chair or out of bed in the morning, and upon taking that first step, feel like your heel has stepped on a tack? Many people experience a feeling of sharp pain which radiates into their arch from their heel and which does not allow them to put their heel on the floor. Sometimes they need to sit back down, stand only on their toes and use the wall for balance. If you can take a few steps, it seems to go away and lessen, allowing you to then resume your activity. Later, throughout your day and after a period of rest, it can happen again. If this sounds familiar you may be suffering from your first attack of heel pain.
Heel pain is a debilitating condition that affects day to day activities. Running and walking both causes stress on the heel because the heel is the part of the foot that hits the ground first. This means that the heel is taking on your entire weight. Diagnosis and treatments for heel pain can be easily found through your podiatrist.
Plantar Fasciitis
One of the main causes of heel pain is a condition known as plantar fasciitis. The plantar fascia is a band of tissue that extends along the bottom of the foot, from the toe to the bottom of the heel. A rip or tear in this ligament can cause inflammation of these tissues, resulting in heel pain. People who do not wear proper fitting shoes are often at risk of developing problems such as plantar fasciitis. Unnecessary stress from ill-fitting shoes, weight change, excessive running, and wearing non-supportive shoes on hard surfaces are all causes of plantar fasciitis.
Achilles Tendonitis
Achilles tendonitis is another cause of heel pain. Similar to plantar fasciitis, inflammation of the Achilles tendon will cause heel pain due to stress fractures and muscle tearing. A lack of flexibility of the ankle and heel is an indicator of Achilles tendonitis. If left untreated, this condition can lead to plantar fasciitis and cause even more pain on your heel.
Heel Spur
A third cause of heel pain is a heel spur. A heel spur occurs when the tissues of the plantar fascia undergo a great deal of stress, leading to a separation of the ligament from the heel bone entirely. This results in a pointed fragment of bone on the ball of the foot, known as a heel spur.
Fungal infection of the toenail, or onychomycosis, typically appears as a gradual change in a toenail’s texture and color that involves brittleness and darkening. The fungal infection itself occurs beneath the surface of the nail. Aside from discoloration, other symptoms include the collection of debris beneath the nail plate, white marks on the nail plate, and a foul odor emanating from the nail. If ignored, the infection can spread into other nails and the skin; in severe cases, it can hinder one’s ability to work or walk.
The toenails are particularly vulnerable to contracting infection in moist environments where people are likely to be walking barefoot, such as around swimming pools, public showers, and locker rooms. Fungal infection may also be more likely to occur in nail beds that have been injured, and sufferers of chronic diseases such as diabetes, circulatory problems, or immunodeficiency conditions are particularly prone to developing fungal nails.
Fungal nails can be primarily prevented by practicing proper hygiene and regularly examining the feet and toes. Carefully washing the feet with soap and water and thoroughly drying the feet afterwards are essential. Other tips include wearing shower shoes in public areas, changing shoes and socks daily, keeping toenails clipped at a short length, wearing breathable shoes that fit properly, wearing moisture-wicking socks, and disinfecting home pedicure tools and instruments used to cut nails.
Fungal nail treatment may vary between patients and the severity of the condition. Your podiatrist may suggest a daily routine of cleansing that spans over a period of time to ease mild infections. Over-the-counter or prescription antifungal agents may also be prescribed, including topical and/or oral medications. Debridement, or the removal of diseased nail matter and debris, may also be performed. In more severe cases, surgical treatment may be needed. In some instances, the temporary removal of the fungal nail allows for the direct application of a topical antifungal to the nail bed. In other cases, a chronically painful fungal nail that has not responded to other treatments may be permanently removed; this allows the infection to be cured and avoids the growth of a deformed nail.
Although it may be tempting to wear flip-flops in warm weather, they are not the best choice of footwear for your feet. Flip-flops may be ideal for the beach, pool, spa, and shared showers, but you should avoid wearing them unless it is completely necessary.
Flip-flops only have a small strip of fabric holding your foot in place, but your toes need a better grip to keep your foot in place. The repetitive gripping can lead to an overuse of your muscles, which could result in tendinitis. This is only one of the many problems that stem from wearing flip-flops too often.
Flip flops aren’t good for extensive walking because they fail to offer arch support, heel cushioning, or shock absorption. As a result, people who wear flip flops are at a higher risk of experiencing an ankle sprain. Additionally, these shoes offer little protection for your feet, putting those who wear them at a greater risk for stubbed toes, glass cuts, and puncture wounds.
Although flip flops aren’t recommended for everyday use by anyone, it is especially important for diabetics to avoid them. A diabetic foot injury can easily become very serious, and it may even lead to amputation.
If you are experiencing pain from wearing flip-flops, you shouldn’t be hesitant to replace them with a more comfortable shoe that offers more support. If your flip-flop foot pain doesn’t go away, you should seek assistance from a podiatrist right away. It is possible that you may have a more serious foot problem such as a stress fracture or arthritis.
