Tarsal tunnel syndrome -- tarsal: meaning the lower ankle area of the foot -- is a condition that usually affects the medial (inside) of the ankle. There are many structures that run through this area, including tendons, veins, arteries and nerves.
Tarsal Tunnel Syndrome occurs when the posterior tibial nerve, as it courses under the ligament at the ankle, becomes inflamed for a variety of reasons, namely: excessive pronation, arthritic problems such as rheumatoid arthritis , trauma, and even obesity.
The symptoms that are characteristic of this disease are persistent burning pain, pain that radiates down to the toes and/or up to the lower leg, and pain that is usually unremitting, in that is does not subside after weight has been removed from the foot.
Other Symptoms include:
- Tingling, burning, or a sensation
similar to an electrical shock
- Numbness
- Pain, including shooting pain
The symptoms are typically felt on the inside of the ankle and/or on
the bottom of the foot. In some people, a symptom may be isolated and occur in just one spot. In others, it may extend to the heel, arch, toes, and even the calf.
Sometimes the symptoms of the syndrome appear suddenly. Often they are brought on or aggravated by overuse of the foot—such as in prolonged standing, walking, exercising, or beginning a new exercise program.
It is very important to seek early treatment if any of the symptoms of tarsal tunnel syndrome occur. If left untreated, the condition progresses and may result in permanent nerve damage. In addition, because the symptoms of tarsal tunnel syndrome can be confused with other conditions, proper evaluation is essential so that correct diagnosis can be made.
Treatment:
Simple techniques to relieve some of the symptoms are ice, anti-inflammatories, immobilization (such as with a cast walking boot) and cortisone injections.
In some cases where the pain is unresolved after conservative measures have been employed, then surgery is utilized.
