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.

Athlete’s foot, or tinea pedis, is a skin disease caused by a fungal infection.  The infection typically occurs between the toes, and the feet are most subject to this disease because shoes best create the warm, dark, and moist environment in which fungus thrives.  Other areas that create a similar environment, such as swimming pools, public showers, and locker rooms; can also promote fungi growth. 

Symptoms of athlete’s foot include dry skin, itching, scaling, inflammation, and blistering.  Sometimes, blisters can evolve into the cracks or breaks in the skin.  The exposed tissue can then create pain, swelling, and discharge.  The spread of infection can cause itching and burning as well.

While athlete’s foot commonly occurs between the toes, it may also spread to the toenails or soles of the feet.  Other parts of the body, such as the groin or underarms, can also become infected if they are touched after the original area of infection is scratched.  Aside from physical contact, athlete’s foot can also spread through the contamination of footwear, clothing or bedsheets.

Proper foot hygiene is essential in preventing athlete’s foot.  You can prevent the fungus from spreading by frequently washing your feet using soap and water, thoroughly drying the feet between the toes, changing shoes and socks every day to reduce moisture, and ensuring that bathroom and shower floors are disinfected.  Other tips include using shower shoes, avoiding walking barefoot in public environments, wearing light and airy shoes, and wearing socks that keep the feet dry.

While treatment for athlete’s foot can involve topical or oral antifungal drugs, mild cases of the infection can be treated by dusting foot powder in shoes and socks.  Any treatment used can be supplemented by frequently bathing the feet and drying the toes.  If proper foot hygiene and self-care do not ease your case of athlete’s foot, contact your podiatrist.  He will determine if the underlying cause of your condition is truly a fungus.  If that is the case, a comprehensive treatment plan may be suggested with the inclusion of prescription antifungal medications.

Diabetes can cause two problems that can potentially affect the feet: Diabetic neuropathy and Peripheral Vascular Disease. Diabetic neuropathy occurs when nerves in your legs and feet become damaged, which prevents you from feeling heat, cold, or pain. The problem with diabetic neuropathy is that a cut or sore on the foot may go unnoticed and the cut may eventually become infected. This condition is also a main cause of foot ulcers. Additionally, Peripheral vascular disease also affects blood flow in the body. Poor blood flow will cause sores and cuts to take longer to heal. Infections that don’t heal do to poor blood flow can potentially cause ulcers or gangrene.

There are certain foot problems that are more commonly found in people with diabetes such as Athlete’s foot, calluses, corns, blisters, bunions, foot ulcers, ingrown toenails, and plantar warts. These conditions can lead to infection and serious complications such as amputation. Fortunately, proper foot care can help prevent these foot problems before they progress into more serious complications.       

Each day you should wash your feet in warm water with a mild soap. When you finish washing your feet, dry them carefully especially between your toes. You should also perform daily foot inspections to ensure you don’t have any redness, blisters, or calluses. Furthermore, if you are diabetic, you should always wear closed-toed shoes or slippers to protect your feet. Practicing these tips will help ensure that your feet are kept healthy and away from infection.

If you have diabetes, contact your podiatrist if you have any of the following symptoms on your feet: changes in skin color, corns or calluses, open sores that are slow to heal, unusual and persistent odor, or changes in skin temperature. Your podiatrist will do a thorough examination of your feet to help treat these problematic conditions.

Ankle foot orthotics are shoe inserts that offer support to control the placement and movement of the ankle, correct deformities, and compensate for weakness. These inserts are used to stabilize the foot and ankle and provide toe clearance during the swing phase of gate.

Athletes often suffer foot problems because their feet are not being supported within the shoe. Ankle and foot orthotics are custom made inserts that alleviate stress on the foot. However custom orthotics should be prescribed by a podiatrist who specializes in customized footwear and orthotics design. These inserts are used by athletes for different reasons. Runners use orthotics to absorb shock at heel contact and to set up the forefoot for push-off. Basketball players wear them to control their forefeet while jumping and running.

The two main types of orthotics are over-the-counter orthotics and custom-made orthotics. To be eligible for custom orthotics, an examination of the foot and ankle will need to be completed. Afterward, both the foot and ankle will need to be casted and fitted for the proper orthotic. When the fitting process is complete, adjustments can be made to make sure everything fits perfectly.

Over the counter orthotics tend to be more popular than custom fit ones. Athletes who have less severe aches and pains in the foot, ankle or lower back area can use the over-the-counter version of orthotics. Unfortunately, over-the-counter orthotics tend to not work in treating severe injuries or ailments. Whenever you suspect you may need an ankle foot orthotic, you should consult with your podiatrist to determine which type of orthotic is right for you.

Running may seem like a simple to do. However, running is actually a complex movement that puts stress on the ligaments, bones, and joints of the body.  Selecting the correct running shoe is important for increasing performance and avoiding risk of injury.  Running shoes should be selected based on your foot type.  Considerations such as trail versus road shoes are important. Your foot type dictates the degree of cushioning, stability and motion control you require.  The most accurate way to learn your foot type is to visit a local shop that specializes in running shoes.  Professionals can measure your arch type, stride and gait and help you with your shoe needs.

The design of running shoes is created around the idea of pronation.  Pronation is the natural rolling movement of your ankle from the outside to inside when your foot strikes the ground.  If you run properly you strike the ground on the outside of your heel and roll in the direction of your big toe before pushing off once more.  Pronation is beneficial because it assists the lower half of your body in absorbing shock and storing energy.  Those considered neutral runners pronate correctly and do not need running shoes that help correct their form.  Neutral runners can choose from a wide variety of shoes, including barefoot or minimal types.  However, those who have arch problems or who adopt an incorrect form while running may experience too much or too little pronation. They may require running shoes that offer additional support.

Those who overpronate experience an over-abundance of ankle rolling.  Even while standing, those who severely overpronate display ankles that are angled inward.  It is not uncommon for them to have flat feet or curved legs.  The tendency to overpronate may cause many injuries.  Areas that tend to become injured are the knees, ankles, and Achilles tendon.  If you find that you have a tendency to overpronate, you should look at shoes that provide extra stability and motion-control.  Motion-control shoes are straight and firm. Shoes of this type do not curve at the tip.  The restricted flexibility along the middle of the shoe prohibits the foot from rolling too far inward as your foot strikes the ground.

A less common problem is underpronation.  Underpronation, also called supination, is when the feet are unable to roll inward during landing.  Those who underpronate have feet that lack flexibility and high arches.  This prevents any kind of shock absorption, even though it does place less rotational stress on ankles and knees.  This added force can cause fractures, ligament tears, and muscle strains because the legs are trying to compensate for the impact.  Those who underpronate need shoes with more cushioning and flexibility.  If you have a tendency to underpronate, selecting stability or motion-control shoes may cause you more problems by continuing to prevent pronation.
