Tarsal tunnel syndrome is a condition in which there is a compression of the posterior tibial nerve. The posterior tibial nerve runs along the inside of the ankle into the foot. Tarsal tunnel syndrome is named for the tarsal tunnel, which is a thin space along the inside of the ankle beside the ankle bones. This space contains various nerves, arteries, and tendons, and includes the posterior tibial nerve. The tibial nerve is the peripheral nerve in the leg responsible for sensation and movement of the foot and calf muscles. In tarsal tunnel syndrome the tibial nerve is compressed, causing tingling or burning, numbness, and pain.

Common causes of tarsal tunnel syndrome involve pressure or an injury. Injuries that produce inflammation and swelling in or around the tunnel may place pressure on the posterior tibial nerve. Direct pressure on the tibial nerve for an extended period of time, sometimes caused by other body structures close by or trauma to the tibial nerve, can result in tarsal tunnel syndrome. Diseases that damage nerves, such as diabetes or arthritis, may cause tarsal tunnel syndrome. Those with flat feet are at risk for developing the condition, as the extra pressure and strain placed on the foot may compress the posterior tibial nerve.

Feeling different sensations in the foot at different times is a common symptom of tarsal tunnel syndrome. An afflicted person may experience pain, tingling, burning or other unusual sensations in the foot of the affected leg. Symptoms are primarily felt on bottom of the foot and/or the inside of the ankle. Symptoms can appear suddenly and may occur due to overuse of the foot.

To diagnose tarsal tunnel syndrome, your podiatrist may examine the foot and tap the posterior tibial nerve to see if symptoms surface. He or she may also order an MRI to determine if a mass is present.

Treating tarsal tunnel syndrome will depend on the decision of your podiatrist. Multiple options are available, however, and can include rest, ice, immobilization, oral medications such as anti-inflammatory drugs (NSAIDS), physical therapy, injection therapy, orthotics, supportive shoes, braces, and surgery.

Cracked heels can make life very frustrating and embarrassing when displaying the bare feet. Aside from being unpleasing to the eye, they can also tear stockings and socks and wear out shoes at a faster rate. When severe, cracked heels may cause pain or infection.

Cracked heels are a problem for those who are athletic, those who may walk a lot, and those who have especially dry skin. Those who use medication that dry the skin, those who swim often, wearing certain types of shoes, and those who are diabetic may have trouble with cracked heels. Seniors whose skin produces less oil may also have trouble with cracked feet. There is no one way to develop cracked feet, and there is no cure.

Today, the market consists of numerous products that have a variety of ingredients to promote healing. Some of these are over-the-counter. Others are prescribed by a doctor, especially for those who have chronic dry feet and heels.

Some doctors recommend wearing socks at night for those with rough skin. This helps further healing, and helps creams stay on longer and better absorb into the skin.

One way to alleviate dryness that causes cracked heels is by using moisturizers both day and night. Another way is to make sure the skin is clean and dry at all times. Using a pumice stone to buff away dead skin before putting on moisturizer can also help. Cracked heels will not respond to the cream unless the outer layer of skin is first removed through exfoliation. After exfoliation, lotion or ointment will be absorbed by the skin more easily.

Foods that produce healing and balance can also help the skin from within. Everything that is put into the body can either help it or hurt it. Taking supplements of omega-3 fatty acids and zinc can also be very beneficial.

Nevertheless, not all products are guaranteed to help treat cracked feet. Seeing a professional is best if other treatments options were unsuccessful. A podiatrist should be able to give the best advice to help with this problem.

Blisters are pockets of fluid that occur under the top layer of your skin. These fluid pockets are usually filled with pus, blood, or serum. Blisters may itch or hurt and can appear as a single bubble or in clusters.

The most common types of blisters are friction blisters. This type of blister may be caused by wearing shoes that are too tight. Friction blisters can also occur on the hands. A change in temperature may also cause blisters on the feet. In the freezing air, frostbite on your toes can lead to blisters, as well as sunburn from hot weather.

The best way to treat a blister is to keep it clean and dry. Most blisters will get better on their own. Once the skin absorbs the fluid within the blister, it will flatten and eventually peel off. You should avoid popping your blister unless you podiatrist does it for you. Additional treatment options include applying an ice pack to the blister or using over-the-counter blister bandages to cover the affected area.

If your blister becomes discolored, inflamed, or worsens it is advised that you speak to your podiatrist. Blisters that are yellow, green, or purple may be infected and require immediate medical attention. Blisters that are abnormally colored may be a sign of a more serious underlying health condition such as herpes.

Corns and Calluses are both hardened layers of thickened skin that develop because of friction. Both ailments are typically found on the feet and may be unsightly. Although they have similarities, corns and calluses are different from each other.

Some causes of corns and calluses may be wearing ill-fitting shoes and not wearing socks. If you wear tight shoes, your feet will constantly be forced to rub against the shoes, causing friction. If you fail to wear socks, you are also causing your feet to endure excess friction.

There are some signs that may help you determine whether you have one of these two conditions. The first symptom is a thick, rough area of skin. Another common symptom is a hardened, raised bump on the foot. You may also experience tenderness or pain under the skin in addition to flaky, dry, or waxy skin.

There are also risk factors that may make someone more prone to developing corns and calluses. If you are already dealing with bunions or hammertoe, you may be more vulnerable to having corns and calluses as well. Other risk factors are foot deformities such as bone spurs, which can cause constant rubbing inside the shoe.

Corns tend to be smaller than calluses and they usually have a hard center surrounded by inflamed skin. They also tend to develop on the parts of the body that don’t bear as much weight such as the tops and sides of toes. Corns may also be painful for those who have them. On the other hand, calluses are rarely painful. These tend to develop on the bottom of the feet and may vary in size and shape.

Fortunately, most people only need treatment for corns and calluses if they are experiencing discomfort. At home treatments for corns and calluses should be avoided, because they will likely lead to infection. If you have either of these ailments it is advised that you consult with your podiatrist to determine the best treatment option for you.

Flatfoot is a foot disorder that is not as straightforward as many people believe.  Various types of flatfoot exist, each with their own varying deformities and symptoms.  The partial or total collapse of the arch, however, is a characteristic common to all types of flatfoot.  Other signs of flatfoot include:

• “Toe drift,” or the pointing outward of the toes and the front part of the foot
• The tilting outward of the heel and the tilting inward of the ankle
• The lifting of the heel off the ground earlier when walking due to a tight Achilles tendon
• Hammertoes
• Bunions

One of the most common types of flatfoot is flexible flatfoot.  This variation usually starts in childhood and progresses as one ages into adulthood.  Flexible flatfoot presents as a foot that is flat when standing, or weight-bearing.  When not standing, the arch returns.  Symptoms of flexible flatfoot include:

• Pain located in the heel, arch, ankle, or along the outside of the foot
• Overpronation, or an ankle that rolls in
• Shin splint, or pain along the shin bone
• General foot aches or fatigue
• Pain located in the lower back, hip, or knee

Your podiatrist will most likely diagnose flatfoot by examining your feet when you stand and sit.  X-rays may be taken to define the severity and help determine the treatment option best for your condition.  Nonsurgical treatments can include activity modification, weight loss, orthotics, immobilization, medications, physical therapy, shoe modifications, and ankle foot orthoses (AFO) devices.  If nonsurgical methods prove ineffective, surgery may be considered.  Multiple surgical procedures can correct flatfoot; and depending on your specific condition, one may be selected alone or combined with other techniques to ensure optimal results.
