tarsal tunnel syndrome
Also known as tibial nerve dysfunction, an uncommon disorder arising from abnormal pressure on the tibial nerve in the foot. Where this nerve curves around the inside of the ankle, it passes through the tarsal tunnel, a space formed between the bones of the ankle joint and bands of supporting fibrous tissue. If this space becomes constricted, the nerve is trapped and compressed. Tarsal tunnel syndrome sometimes occurs when injury, or stress from overactivity, damages foot structures. It is also more common in people with flat feet. usual symptoms are pain and a burning or tingling sensation on the sole of the foot.
Rest and anti-inflammatory drugs may be all that is needed. Persistent cases may be treated by physiotherapy, injections of corticosteroid drugs or, possibly, surgery, to open up the tarsal tunnel.
