Tarsal Tunnel Syndrome

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.

Poor blood circulation in the feet and legs is often caused by peripheral artery disease (PAD), which is usually the result of a buildup of plaque in the arteries. Plaque buildup, or atherosclerosis, can be the result of excess calcium and cholesterol in the bloodstream. This restricts how much blood can flow through arteries. Reduced blood flow to a certain area of the body severely limits the amount of oxygen and nutrients that part of the body receives. This leads to degeneration in the muscles and other tissues. Sometimes, poor blood circulation in the feet and legs can be caused by other conditions, such as the damaging or inflammation of blood vessels, known as vasculitis.

The lack of oxygen and nutrients caused by poor blood circulation can restrict muscle growth and development, as well as cause muscle pain and cramps, weakness, and stiffness. Other common symptoms include numbness in the legs and feet, skin discoloration in the affected limbs, slower nail and hair growth, and erectile dysfunction in men. In more severe cases of PAD, pain can be present even when a person isn't exercising, and may range from mildly uncomfortable to completely debilitating.

Poor blood circulation in the feet and legs is more common in those who are overweight or obese, have diabetes, high blood pressure, high cholesterol, who smoke, or who have a family history of PAD or related conditions such as a heart attack, stroke, etc. Diabetes and smoking place a person at greatest risk for developing poor blood circulation, although advanced age, over 50, can also increase risk.

If you are experiencing poor blood circulation in the feet and legs caused by PAD, it is important to make changes to your lifestyle in order to reduce your risk of experiencing a heart attack or stroke caused by this condition. If you smoke, quit completely. This will increase the amount of oxygen in your bloodstream. Exercising and reducing the saturated fats in your diet. Saturated fats come from fatty meats, fried foods, whole milk, etc., can make a difference in improving blood circulation in feet. It is also important to avoid developing influenza and to carefully control your blood sugar if you have diabetes.

Your doctor may recommend combining lifestyle changes with a prescription medication regimen to improve blood circulation. The most commonly-used medications for PAD are called statins and work by blocking the amount of enzymes in your body that produce cholesterol. They are known by the brand names Zocor, Lipitor, Crestor, and others.

Plantar Fasciitis

The plantar fascia is a connective tissue in the heel that stretches across the bottom length of your foot. Plantar fasciitis occurs when the connective tissue becomes inflamed, causing heel pain and discomfort during physical activity. Although the condition is completely treatable, traditional methods can take up to a year to start becoming effective.

Plantar fasciitis is caused by a number of everyday activities, so understanding the condition is important for managing and treating it. One of the most common causes of plantar fasciitis is excessive running, especially with improper fitting or non-supportive shoes. Too much exercise can lead to the plantar fascia being overworked and overstretched, which can cause tears in the tissue. Along with improper fitting shoes, pronation, the rolling of the feet inward, is a common cause of plantar fasciitis. If not treated properly, the plantar fascia becomes overstretched and starts to tear, causing inflammation.

Despite the common causes of plantar fasciitis, there are many different treatment options. For less severe cases, conservative home remedies include taking anti-inflammatory drugs to alleviate pain, applying ice packs to the bottom of your foot and heel, slowly stretching and exercising your feet to re-strengthen the tissue, and using orthotic devices are all ways to help manage your plantar fasciitis.

For more severe cases, shockwave therapy has become a common solution for plantar fasciitis. Shockwave therapy can effectively break up the tissue on the bottom of your foot which facilitates healing and regeneration. This fights the chronic pain caused by plantar fasciitis. Even if this doesn’t work, surgery is always a final option. Surgery on the tissue itself can be done to permanently correct the issue and stop the inflammation and pain in your heels.

No matter what the case may be, consulting your podiatrist is the first and best step to recovery. Even the slightest amount of heel pain could be the first stage of plantar fasciitis. Untreated symptoms can lead to the tearing and overstretching of tissue. Because the tearing of tissue can be compounded if it remains ignored, it can evolve into a severe case. The solution is early detection and early treatment. Talk to your podiatrist about the possibilities of plantar fasciitis if you’re experiencing heel pain.

Hyperhidrosis of the Feet

Hyperhidrosis of the feet, also termed plantar hyperhidrosis, is characterized by excessive sweating of the feet that can be onset by any cause, such as exercise, fever, or anxiety. Most people suffering from hyperhidrosis of the feet also experience hyperhidrosis of the hands, or palmar hyperhidrosis. Approximately 1-2% of Americans suffer from this disorder.

Sweating is a healthy process utilized by the body in order to cool itself and maintain a proper internal temperature, which is controlled by the sympathetic nervous system. In individuals with hyperhidrosis, the sympathetic nervous system works in "overdrive", producing far more sweat than is actually needed.

Plantar hyperhidrosis is considered primary hyperhidrosis. Secondary hyperhidrosis refers to excessive sweating that occurs in an area other than the feet, hands, or armpits, and this indicates that is related to another medical condition, such as menopause, hyperthyroidism, or Parkinson's disease.

Symptoms of hyperhidrosis of the feet can include foot odor, athlete's foot, infections, and blisters. Because of the continual moisture, shoes and socks can rot which creates an additional foul odor and can ruin the material, requiring shoes and socks to be replaced frequently. In addition to the physical symptoms, emotional health is often affected as this disorder can be very embarrassing.

If left untreated, hyperhidrosis will usually persist throughout an individual's life. However, there are several treatment options available. A common first approach to treating hyperhidrosis of the feet is a topical ointment. Aluminum chloride, an ingredient found in antiperspirants, can be effective at treating hyperhidrosis if used in high concentration and applied to the foot daily. Some individuals can experience relief this way, while others encounter extreme irritation and are unable to use the product. Another procedure is the use of Botulinum Toxin A, commonly referred to as Botox. This is injected directly into the foot, and is effective at minimizing the sweat glands in the injected area. These injections must be repeated every 4 to 9 months.

If these treatments are ineffective, oral prescription medications may be taken in an effort to alleviate the symptoms. Again, some will experience relief while others do not. Going barefoot reportedly provides relief for most sufferers.

A final approach to combating hyperhidrosis of the feet is through surgery. Surgery has been less successful on patients with plantar hyperhidrosis than on those with palmar hyperhidrosis. It is only recommended when sweating is severe and other treatments have failed to work. This kind of surgery usually involves going into the central nervous system, and cutting nerves to stop the transmission of signals telling the foot to sweat.
