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.

A podiatrist will be able to address a variety of rare foot conditions, particularly the ones that affect children. The most common are Kohler’s disease, Maffucci syndrome, and Freiberg’s disease. They can be properly diagnosed by having an X-ray taken, but in more serious cases an MRI may be needed. Kohler’s disease generally affects younger boys and bone deterioration may result from an interruption of blood supply. Children who have Kohler’s disease may find relief when the affected foot is rested, and a special boot is worn. Benign growths in the long bones of a child’s foot may lead to the development of bone lesions, and this is known as Maffucci syndrome. People who have this condition find mild relief when custom-made orthotics are worn. Freiberg’s disease targets the ball of the foot and can typically affect pre-teen and teenage girls. The metatarsal bone becomes deteriorated and flattened, and common symptoms include swelling and stiffness. A cast is often necessary to wear with this disease as it can help to reduce existing pain. Erythromelalgia is a rare foot condition, and its cause is unknown. Symptoms of this disease can include intense burning pain and the feet may appear red or feel warm. Relief may be found when the affected foot is immersed in ice water. It can also be beneficial to elevate the foot frequently. If your child complains of foot pain, it is strongly suggested that you consult with a podiatrist who can diagnose and treat rare foot conditions. 

A neuroma is a thickening of nerve tissue and can develop throughout the body.  In the foot, the most common neuroma is a Morton’s neuroma; this typically forms between the third and fourth toes.  The thickening of the nerve is typically caused by compression and irritation of the nerve; this thickening can in turn cause enlargement and, in some cases, nerve damage.

Neuromas can be caused by anything that causes compression or irritation of the nerve.  A common cause is wearing shoes with tapered toe boxes or high heels that force the toes into the toe boxes.  Physical activities that involve repeated pressure to the foot, such as running or basketball, can also create neuromas.  Those with foot deformities, such as bunions, hammertoes, or flatfeet, are more likely to develop the condition.

Symptoms of Morton’s neuroma include tingling, burning, numbness, pain, and the feeling that either something is inside the ball of the foot or that something in one’s shoe or sock is bunched up.  Symptoms typically begin gradually and can even go away temporarily by removing one’s shoes or massaging the foot.  An increase in the intensity of symptoms correlates with the increasing growth of the neuroma.

Treatment for Morton’s neuroma can vary between patients and the severity of the condition.  For mild to moderate cases, padding, icing, orthotics, activity modifications, shoe modifications, medications, and injection therapy may be suggested or prescribed.  Patients who have not responded successfully to less invasive treatments may require surgery to properly treat their condition.  The severity of your condition will determine the procedure performed and the length of recovery afterwards.

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.

Neuropathy is the weakness, numbness, and pain in the hands and feet due to damage to the peripheral nerves. The peripheral nerves are responsible for sending information from the brain and spinal cord to the rest of your body. Causes of Neuropathy include: traumatic injuries, infections, metabolic problems, exposure to toxins, and diabetes.

Diabetes is the most common cause, with more than half of the diabetic population developing some type of neuropathy. There are several types of neuropathy and they vary based on the damage of the nerves. Mononeuropathy is classified as only one nerve being damaged. When multiple nerves are affected, it is referred as polyneuropathy. One of the types of polyneuropathy is distal symmetric polyneuropathy. It is the most common for people with diabetes and starts when the nerves furthest away from the central nervous begin to malfunction. The symptoms begin with pain and numbness in the feet and then they travel up to the legs. A rarer form of polyneuropathy is acute symmetrical peripheral neuropathy, which is a severe type that affects nerves throughout the body and is highly associated with Guillain-Barre syndrome, an autoimmune disorder that attacks the peripheral nervous system and can be fatal. Although there are many types of neuropathy, most of them share the same symptoms such as pain, extreme sensitivity to touch, lack of coordination, muscle weakness, dizziness, and digestive problems. Since neuropathy affects the nerves, those affected should be careful of burns, infection and falling, as depleted sensations disguise such ailments.

The best way to prevent neuropathy is to manage any medical conditions such as diabetes, alcoholism, or rheumatoid arthritis. Creating and managing a healthy lifestyle can also go a long way. Having a healthy diet full of fruits, vegetables, whole grains and lean protein can keep the nerves healthy. These types of food have the nutrients to prevent neuropathy. Regularly exercising can help as well, but it is best to consult with a doctor about the right amount. In addition to diet and exercise, avoiding risk factors will also prevent neuropathy. This includes repetitive motions, cramped positions, exposure to toxic chemicals, smoking and overindulging on alcohol.
