The tarsal canal syndrome also called tarsal tunnel syndrome, corresponds to side effects from the compression of the plantar nerves in the foot, in the area behind the medial malleolus. Tarsal canal syndrome triggers pain in the sole of the foot as well as paresthesia
, a tingling sensation or numbness. The constriction can be caused by a cyst, a malunion after a fracture
, or ligament thickening after a sprain
. Wearing orthotics, in combination with analgesics
, can be effective in reducing pain.
