Tinel's sign (ankle) is positive when there is what finding?

Explanation:
Tinel's sign at the ankle checks for nerve irritation by tapping a nerve to see if it reproduces symptoms in its sensory distribution. When a nerve like the posterior tibial nerve is irritated or compressed in the tarsal tunnel, tapping can provoke numbness or tingling in the foot. That sensory disturbance in the foot is the classic positive finding. Pain in the shank, thigh paresthesias, or pain at the Achilles tendon don’t reflect distal nerve irritation patterns, so they’re not consistent with a positive ankle Tinel’s sign.
