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 forefoot is composed of five metatarsal bones and fourteen phalanges. Each toe has three phalanges except for the big toe which only has two. Our toes play an essential role to the walking process, which is why a broken toe could seriously disrupt one’s ability to move around. Toe fractures are common and can be very painful. Fortunately, these injuries rarely require surgery and usually heal with rest and a change in activity.

Broken toes typically result from a traumatic event such as falling, stubbing the toe, or dropping something on the toe. Traumatic toe fractures may be categorized as either minor or severe fractures. At times, one may hear a “pop” or “crack” sound when the bone breaks. Common symptoms of a traumatic toe fracture include pain, throbbing, bruising, swelling, and redness.

Another type of toe fractures is a stress fracture. These injuries usually appear in the form of small hairline breaks on the bone. Stress fractures develop after repetitive activity instead of a single injury. Stress fractures occur when the muscles in the bone become too weak to absorb impact. Consequently, the toe bone becomes vulnerable to any pressure and impact it endures. Symptoms for a stress fracture in the toe include swelling without bruising, tenderness to the touch, pain that goes away with rest, and pain after walking or running.

If you suspect that you have a broken toe, you should make an appointment with your podiatrist. He or she will likely diagnose you by performing a physical exam and an X-ray. Treatment for a broken toe may include the R.I.C.E. method, buddy taping, surgery, or antibiotics. The R.I.C.E. method (Rest, Ice, Compression, and Elevation) is a common treatment method for many injuries because it decreases pain. Buddy tapping involves wrapping the injured toe next to an adjacent toe to keep it supported and protected. These two methods have proven to be effective in the healing process for toe fractures. The estimated healing time for a broken toe is approximately four to six weeks. If the injury becomes infected or requires surgery, the estimated healing time may take eight weeks or more. 

A bunion is an enlargement of the base joint of the toe that connects to the foot, often formed from a bony growth or a patch of swollen tissues. It is caused by the inward shifting of the bones in the big toe, toward the other toes of the foot. This shift can cause a serious amount of pain and discomfort. The area around the big toe can become inflamed, red, and painful.

Bunions are most commonly formed in people who are already genetically predisposed to them or other kinds of bone displacements. Existing bunions can be worsened by wearing improperly fitting shoes. Trying to cram your feet into high heels or running or walking in a way that causes too much stress on the feet can exacerbate bunion development. High heels not only push the big toe inward, but shift one's body weight and center of gravity towards the edge of the feet and toes, expediting bone displacement.

A podiatrist knowledgeable in foot structure and biomechanics will be able to quickly diagnose bunions. Bunions must be distinguished from gout or arthritic conditions, so blood tests may be necessary. The podiatrist may order a radiological exam to provide an image of the bone structure. If the x-ray demonstrates an enlargement of the joint near the base of the toe and a shifting toward the smaller toes, this is indicative of a bunion.

Wearing wider shoes can reduce pressure on the bunion and minimize pain, and high heeled shoes should be eliminated for a period of time. This may be enough to eliminate the pain associated with bunions; however, if pain persists, anti-inflammatory drugs may be prescribed. Severe pain may require an injection of steroids near the bunion. Orthotics for shoes may be prescribed which, by altering the pressure on the foot, can be helpful in reducing pain. These do not correct the problem; but by eliminating the pain, they can provide relief.

For cases that do not respond to these methods of treatment, surgery can be done to reposition the toe. A surgeon may do this by taking out a section of bone or by rearranging the ligaments and tendons in the toe to help keep it properly aligned. It may be necessary even after surgery to wear more comfortable shoes that avoid placing pressure on the toe, as the big toe may move back to its former orientation toward the smaller toes.

Athlete’s foot is a type of fungal infection that affects the skin on the feet. It is caused when the tinea fungus grows on the foot. It is possible to catch the fungus through direct contact with someone who has it or by touching a surface that is contaminated with it. This type of fungus thrives in warm, moist environments such as showers, locker room floors, and swimming pools. Your risk of getting it may also increase by wearing tight-fitting, closed-toe shoes, or by having sweaty feet.

Symptoms of athlete’s foot include itching, stinging or burning sensations between the toes. You may also experience toenails that are discolored, thick, crumbly, or toenails that pull away from the nail bed.

Your podiatrist may diagnose athlete’s foot by detecting these symptoms or by doing a skin test to see if there is a fungal infection present. The most common exam used to detect Athlete’s foot is a skin lesion potassium hydroxide exam. To use this method, your doctor will scrape off a small area of the infected skin and place it into potassium hydroxide. The potassium hydroxide will destroy the normal cells and leave the fungal cells untouched so that they are visible under a microscope.

There are a variety of treatment options for athlete’s foot. Some medications are miconazole (Desenex), terbinafine (Lamisil AT), clotrimazole (Lotrimin AF), butenafine (Lotrimin Ultra), and tolnaftate (Tinactin). While these options may be able to treat your fungus, it is best that you consult with a podiatrist in order to see which treatment option may work best for you.

In some cases, Athlete’s foot may lead to complications. A severe complication would be a secondary bacterial infection which may cause your foot to become swollen, painful, and hot.

There are ways that you can prevent athlete’s foot. Washing your feet with soap and water each day and drying them thoroughly is an effective way to prevent infections. You also shouldn’t share socks, shoes, or towels with other people. It is crucial that you wear shower sandals in public showers, around swimming pools, and in other public places. Additionally, you should make sure you wear shoes that can breathe and change your socks when your feet become sweaty. If you suspect that you have Athlete’s foot, you should seek help from a podiatrist as soon as possible.

Athlete’s foot is an extremely contagious infection caused by a fungus that results in itching, burning, dry, and flaking feet. The fungus that causes athlete’s foot is known as tinea pedis and thrives in moist, dark areas such as shower floors, gyms, socks and shoes, commons areas, public changing areas, bathrooms, dormitory style houses, locker rooms, and public swimming pools. Athlete’s foot is difficult to treat as well because of the highly contagious and recurrent nature of the fungus.

Tinea is the same fungus that causes ringworm, and is spread by direct contact with an infected body part, contaminated clothing, or by touching other objects and body parts that have been exposed to the fungus. Because the feet are an ideal place for tinea to grow and spread, this is the most commonly affected area.  It is, however, known to grow in other places. The term athlete’s foot describes tinea that grows strictly on the feet.

The most commonly infected body parts are the hands, groin, and scalp, as well as the feet. Around 70% of the population suffer from tinea infections at some point in their lives, however not all of these cases are athlete’s foot. Just like any other ailment, some people are more likely to get it than others, such as people with a history of tinea infections or other skin infections, both recurring and non-recurring ones. The extent to which a person experiences regrowth and recurrent tinea infections varies from person to person.

Sometimes people will not even know that they are infected with tinea or that they have athlete’s foot because of a lack of symptoms. However, most experience mild to moderate flaking, itching, redness, and burning. However, some of the more severe symptoms include cracking and bleeding skin, intense itching and burning, pain while walking or standing, and even blistering.

Because of the recurring nature of the tinea fungus and the athlete’s foot it causes, the best way to treat this condition is with prevention. You can take some preventative measures such as wearing flip flops or sandals in locker rooms and public showers to reduce contact with the floor. It also helps to keep clean, dry feet while allowing them to breathe. Using powders to keep your feet dry is a good idea, as well as keeping your feet exposed to light and cool air, to prevent the growth of tinea. If you do happen to get athlete’s foot, opt for using topical medicated creams, ointments or sprays. These treatments help eliminate and prevent it from coming back.
