Diagnosis of Tarsal Tunnel Syndrome
The foot and ankle surgeon will examine the foot to arrive at a diagnosis and determine if there is any loss of feeling. During this examination, the surgeon will position the foot and tap on the nerve to see if the symptoms can be reproduced. He or she will also press on the area to help determine if a small mass is present.

Advanced imaging studies may be ordered if a mass is suspected or if initial treatment does not reduce the symptoms. Studies used to evaluate nerve problems-electromyography and nerve conduction velocity (EMG/NCV)-may be ordered if the condition shows no improvement with nonsurgical treatment.
