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. 

Both running and walking are great exercises, but should a person wear the same shoes for both activities? The answer is no, because there is a difference between the way a person’s feet hit the ground when they are walking and when they are running. Therefore, the shoes for each activity are designed differently. Before you begin any exercise program it is always recommended that you speak with your doctor or podiatrist.

Walking is a low impact exercise that is often recommended by doctors to their patients. While walking is a simple activity, it still requires some degree of preparation. If you think about walking and how your feet strike the ground as you move, you will notice that your heel hits the ground first before your foot continues to roll forward and your next step begins. Because of this rolling motion, walking shoes are designed to be more flexible than running shoes. This flexibility helps the walker push off with each step taken.

Because the heel hits the ground first when you walk, walking shoes are designed to absorb most of the shock. Walking shoes should therefore have a beveled or angled heel. The angle of the heel helps absorb the shock and reduces pressure from the ankles. This is especially important for speed walkers, as their feet will hit the ground twice as often as the normal walker.

When people decide to run as a hobby or for their health, they must first realize that running is a high impact exercise. If not done with the proper equipment, running may cause damage to the feet and legs. Running shoes are designed to be more lightweight and to have thicker soles. The thicker soles act as shock absorbers for the rest of the body. Walking shoes often do not have the proper arch support that running shoes do.

A proper fitting shoe can make or break a runner or a walker. If the shoes are too big, their feet will slide back and forth inside the shoe and cause blisters. Whether you will be running or walking, the right equipment can make all of the difference in the world.

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.
