Athlete’s Foot
Athlete’s foot, or tinea pedis, is a skin disease caused by a fungal infection. The infection typically occurs between the toes, and the feet are most subject to this disease because shoes best create the warm, dark, and moist environment in which fungus thrives. Other areas that create a similar environment, such as swimming pools, public showers, and locker rooms; can also promote fungi growth.
Symptoms of athlete’s foot include dry skin, itching, scaling, inflammation, and blistering. Sometimes, blisters can evolve into the cracks or breaks in the skin. The exposed tissue can then create pain, swelling, and discharge. The spread of infection can cause itching and burning as well.
While athlete’s foot commonly occurs between the toes, it may also spread to the toenails or soles of the feet. Other parts of the body, such as the groin or underarms, can also become infected if they are touched after the original area of infection is scratched. Aside from physical contact, athlete’s foot can also spread through the contamination of footwear, clothing or bedsheets.
Proper foot hygiene is essential in preventing athlete’s foot. You can prevent the fungus from spreading by frequently washing your feet using soap and water, thoroughly drying the feet between the toes, changing shoes and socks every day to reduce moisture, and ensuring that bathroom and shower floors are disinfected. Other tips include using shower shoes, avoiding walking barefoot in public environments, wearing light and airy shoes, and wearing socks that keep the feet dry.
While treatment for athlete’s foot can involve topical or oral antifungal drugs, mild cases of the infection can be treated by dusting foot powder in shoes and socks. Any treatment used can be supplemented by frequently bathing the feet and drying the toes. If proper foot hygiene and self-care do not ease your case of athlete’s foot, contact your podiatrist. He will determine if the underlying cause of your condition is truly a fungus. If that is the case, a comprehensive treatment plan may be suggested with the inclusion of prescription antifungal medications.
Hyperhidrosis of the Feet
Each foot, on average, has about 250,000 eccrine sweat glands that produce half a pint of sweat each day. Sweating is a natural and important bodily function. It regulates the body’s temperature by cooling the skin so that it does not overheat. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than what is required. People with plantar hyperhidrosis experience an excess amount of sweat on their feet. It is estimated that 2% to 3% of all Americans suffer from some form of hyperhidrosis. This condition is often caused by neurologic, endocrine, infectious, and other systemic disease. Other factors that may trigger the condition are heat and emotions.
People with hyperhidrosis may notice an overabundance of sweat on their feet, along with a strong odor. The feet may also have a wet appearance coupled with infections such as athlete’s foot or toenail fungus. The sweat may even appear in low temperatures, such as during the winter months. People with plantar hyperhidrosis often need to change their socks several times throughout the day.
The specific cause of hyperhidrosis is unknown, and many believe it may be caused by over-activity. However, others believe the condition is genetic. Caffeine and nicotine are known to cause excitement and nervousness which are two emotions that may make the condition worse.
If you are looking to treat your hyperhidrosis the most important thing you should do is wash your feet every day. You may even need to wash your feet twice a day, if necessary. You should also make sure you are wearing the right socks. Wool and cotton socks are both known to be good for ventilation, meaning they allow the feet to breathe. You should avoid socks made from nylon which trap moisture and lead to sogginess. Other common treatment options are over-the-counter antiperspirants that contain a low dose of metal salt. In some cases, prescription strength antiperspirants that contain aluminum chloride hexahydrate may be necessary. In severe cases, surgery may be required.
Untreated hyperhidrosis can easily lead to complications. Some complications that may arise from the disorder include nail infections, warts, and bacterial infections. Consequently, it is important that you seek treatment from your podiatrist if you suspect that you may have plantar hyperhidrosis.
Achilles Tendon Injuries
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.
Flat Feet
Flatfoot is a foot condition in which the arch of the foot has either partially or totally dropped or has never developed. While it is common in babies and small children, it can become a problem for them in adulthood if the arch never forms. For adults, the development of flat feet can be brought upon by injury, as a result of pregnancy due to increased elasticity, or obesity. Those who have health concerns such as rheumatoid arthritis or diabetes may also be at greater risk for developing the condition.
If you suspect that you have flat feet, it is best to consult your podiatrist. Your foot doctor will examine the suspected foot and observe how it looks while you sit and stand. He or she may take an X-ray to determine how serious the condition is. Some common signs of flatfoot include toe drift, in which the toes and front part of the foot point outward, a short Achilles tendon, and a heel that tilts outwardly while the ankle tilts inward.
Once flatfoot has been diagnosed, your podiatrist may suggest one of several treatment options. Flat feet can be rigid, in which the feet appear to have no arch even when the person is not standing; or flexible, in which the person appears to have an arch while not standing, but once standing the arch disappears. Those with flexible flatfoot may be told to reduce any activities that cause pain and to avoid extended periods of walking or standing. Another suggestion may be weight loss, as excessive weight may be placing pressure on the arches
In few cases, if the condition is severe and all other methods have been exhausted surgery may be required. This is normally avoided, however, due to a lengthy recovery time and high cost.
