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.

The feet, being the foundation of the body, carry all of the body’s weight and are therefore prone to experiencing pain and discomfort. If you are experiencing foot pain, it is important to determine where in the foot you are experiencing this pain to help discover the cause of it. While pain can be experienced virtually anywhere in the foot, the most common sites of foot pain are in the heel and ankle.   

Heel pain can be due to a multitude of conditions including plantar fasciitis, Achilles tendinitis, and heel spurs. Pain experienced in the ankle can be a sign of an ankle sprain, arthritis, gout, ankle instability, ankle fracture, or nerve compression. In more serious cases, pain in the foot can be a sign of improper alignment or an infection.

Foot pain can be accompanied by symptoms including redness, swelling, stiffness and warmth in the affected area. Whether the pain can be described as sharp or dull depends on the foot condition behind it. It is important to visit your local podiatrist if your foot pain and its accompanying symptoms persist and do not improve over time.

Depending on the location and condition of your foot pain, your podiatrist may prescribe certain treatments. These treatments can include but are not limited to prescription or over-the-counter drugs and medications, certain therapies, cortisone injections, or surgery.

If you are experiencing persistent foot pain, it is important to consult with your foot and ankle doctor to determine the cause and location. He or she will then prescribe the best treatment for you. While milder cases of foot pain may respond well to rest and at-home treatments, more serious cases may take some time to fully recover.

Heel spurs are the result of calcium deposits that cause bony protrusions on the underside of the heel. Heel spurs are usually painless, but they have the potential to cause heel pain. Heel spurs tend to be associated with plantar fasciitis, which is a condition that causes inflammation of the band of connective tissue that runs along the bottom of the foot. They most often occur to athletes whose sports involve a lot of running and jumping.

Some risk factors for developing heel spurs include running and jogging on hard surfaces, being obese, wearing poorly fitting shoes, or having walking gait abnormalities.

It is possible to have a heel spur without showing signs of any symptoms. However, if inflammation develops at the point of the spur’s formation, you may have pain while walking or running. In terms of diagnosis, sometimes all a doctor needs to know is that the patient is experiencing a sharp pain localized to the heel to diagnose a heel spur. Other times, an x-ray may be needed to confirm the presence of a heel spur.

Heel spurs can be prevented by wearing well-fitting shoes that have shock-absorbent soles. You should also be sure that you are choosing the right shoe for the activity you want to partake in; for example, do not wear walking shoes when you want to go on a run. Additionally, maintaining a healthy weight can be beneficial toward preventing heel spurs, as it will prevent an excess amount of pressure being placed on the ligaments.

There are a variety of treatment options for people with heel spurs. Some of these include stretching exercises, physical therapy, shoe inserts, or taping and strapping to rest stressed muscles and tendons. If you have heel pain that lasts longer than a month, don’t hesitate to seek help from a podiatrist. Your doctor can help you determine which treatment option is best for you.

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.

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.
