Neuropathy is a condition in which the nerves in the body become damaged from a number of different illnesses. Nerves from any part of the body, including the foot, can be damaged. There are several forms of neuropathy including peripheral neuropathy, cranial neuropathy, focal neuropathy, and autonomic neuropathy. Furthermore there is also mononeuropathy and polyneuropathy. Mononeuropathies affect one nerve while polyneuropathies affect several nerves. Causes of neuropathy include physical injury, diseases, cancers, infections, diabetes, toxic substances, and disorders. It is peripheral neuropathy that affects the feet.

The symptoms of neuropathy vary greatly and can be minor such as numbness, sensation loss, prickling, and tingling sensations. More painful symptoms include throbbing, burning, freezing, and sharp pains. The most severe symptoms can be muscle weakness/paralysis, problems with coordination, and falling.

Podiatrists rely upon a full medical history and a neurological examination to diagnose peripheral neuropathy in the foot. More tests that may be used include nerve function tests to test nerve damage, blood tests to detect diabetes or vitamin deficiencies. Imaging tests, such as CT or MRI scans, might be used to look for abnormalities, and finally nerve or skin biopsies could also be taken.

Treatment depends upon the causes of neuropathy. If the neuropathy was caused by vitamin deficiency, diabetes, infection, or toxic substances, addressing those conditions can lead to the nerve healing and sensation returning to the area. However if the nerve has died, then sensation may never come back to the area. Pain medication may be prescribed for less serious symptoms. Topical creams may also be tried to bring back sensation. Electrical nerve stimulation may be used for a period of time to stimulate nerves. Physical therapy can strengthen muscle and improve movement. Finally surgery might be necessary if pressure on the nerve is causing the neuropathy.

If you are experiencing sensation loss, numbness, tingling, or burning sensations in your feet, you may be experiencing neuropathy. Be sure to talk to a podiatrist to be diagnosed right away.

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.

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.

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.

A congenital foot problem is a problem affecting the feet, toes, and/or ankle that a child is born with. Several issues with a child’s feet can occur congenitally. Such problems include clubfoot, vertical talus, tarsal coalition, polydactyly, macrodactyly, and cleft foot. Some of these problems have a genetic basis, with someone in their family history having a gene causing the condition, and some are simply an anomaly.

The following are specifics about a few of these conditions:

-    Clubfoot, also called congenital talipes equinovarus or talipes equinovarus, is When the tendons of the foot shorten, the bones are of an unusual shape, and the Achilles tendon is tight, causing an inward and downward pointing of the foot. The soles of the feet might also face each other. In most cases of clubfoot, both feet are affected. If not treated, the affected child will walk on the sides of their feet or ankles.

-    Polydactyly is a condition where the child has more than five fingers or toes on either or both feet. Presentation usually consists of a nubbin or small lump of tissue without a bone, a toe that is partially formed but has no joints, or an extra toe.

-    Vertical talus is where the talus bone forms in the wrong position, other bones in the foot do not line up properly, the front of the foot points up, and the bottom of the foot is stiff, has no arch, and usually curves out. This can occur in one or both feet and if left untreated, can lead to serious disability or discomfort as the child grows.

-    Tarsal coalition is when there is an abnormal connection of two or more bones in the foot leading to severe, rigid flatfoot. The tarsal bones, located toward the back of the foot and in the heel, are the ones affected. This condition is often present at birth, but signs of the disorder usually come on in early adolescence.

-    Cleft foot is a rare condition where the foot has missing toes, a V-shaped cleft, and other anatomical differences. Surgery can often help improve the foot’s function since the heel remains normal and is what is most needed for walking. The main issues with this affliction are whether the affected foot can fit into a shoe and the shape and appearance of the foot.

-    Macrodactyly is when the toes are abnormally large due to overgrowth of the underlying bone or soft tissue. Having this condition makes it harder for the child to use the affected foot for certain activities.

Foot and ankle pain can be a nuisance in a person’s life, especially if it happens frequently. The best way to prevent this type of pain, is to exercise often. Regular exercise of the foot includes stretching and strength exercises. Stretching exercises can help prevent injuries such as a sprained ankle, while strength exercises can prevent ailments such as plantar fasciitis.

Stretching exercises can help improve flexibility and the foot and ankle’s range of motion. These exercises can certainly help with those who participate in high-energy activities such as sports. Many athletes routinely perform foot and ankle exercises to prevent injuries like sprained ankles, which are common injuries where the tendons in the ankle are over stretched. Strength exercises help develop foot muscles for better support and protection.

Most exercises are simple and can be done at home, either standing or sitting. One chair exercise is called “limber up”. In this exercise, a person would start by sitting down with their feet flat on the floor. Then lift one leg up so the feet are not touching the floor, then rotate your foot clockwise 15-20 times, and 15-20 times counterclockwise. Repeat the same process with the opposite leg. Another sitting exercise helps stretch the back of your heel and requires an exercise band. It begins by looping the band around a heavy piece of furniture, or something stable that will not be moved when the band is tugged or pulled. Then sit directly in front of it, and slide one foot into the loop, so that the band curves around the forefoot. Start by pulling the forefoot back and holding it for 5-10 seconds. Doing this 10-15 times on each foot, will stretch the back of your heel, increasing your flexibility.

Foot exercises that require standing are also just as easy and simple. Referred as the “Achilles Stretch”, this exercise stretches the Achilles tendon, making it more flexible, helping prevent foot, ankle, and leg pain. It begins by first standing and facing the wall, with the arms outstretched and the palms on the wall. Then place one foot behind another keeping the back leg straight, and the forward leg bending at the knee. Make sure both heels are flat on the floor and adjust your stance accordingly. With your hips, lean forward to feel the stretch, you can also adjust the distance from your feet to feel the stretch in various parts of the calf. Make sure to hold the stretch for about 30 seconds and repeat the same process 3 times with each leg. An even easier foot exercise is simply walking on sand. Walking barefoot on sand both strengthens and stretches your feet.

Doing these exercises regularly can help prevent many foot and ankle problems. Other foot exercises can even relieve pain. For example, those affected with plantar fasciitis can simply sit down on a chair, and then place a tennis ball below their affected foot. By rolling the ball under the foot, and increasing or decreasing pressure, pain will be relieved. With any exercise, it is always important to do a small warmup such as walking a few laps around the house to get the blood flowing. If after doing an exercise to relieve pain such as the tennis ball exercise, or are unsure that your execution is correct, be sure to contact a podiatrist for further instruction.
