What is tarsal tunnel syndrome?
Tarsal tunnel syndrome is a nerve compression disorder in which the main nerve to your foot gets pinched in a tight location. The tibial nerve branches into three nerves in the ankle -- the medial plantar, lateral plantar, and calcaneal nerves. Patients may present with slightly different symptoms, but most have some component of numbness, tingling, burning pain, or sharp stabbing electrical type pains that radiate into the sole of the foot and the toes. It is often worse with activities and better with rest.
