Fibromyalgia and Tinel's sign in the foot.
In the physical examination of the patient suspected of having tarsal tunnel syndrome, the podiatric physician relies on Tinel's sign: tapping the posterior tibial nerve in the tarsal tunnel should produce a distally radiating sensation if the nerve is pathologically compressed at this location. The American College of Rheumatology recognizes fibromyalgia as a condition characterized by multiple "tender points" on physical examination. This report compares the locations of the 18 critical diagnostic fibromyalgia points with known sites of anatomical entrapment of peripheral nerves in the lower extremity. We also describe a patient with both fibromyalgia and tarsal tunnel syndrome. Tinel's sign in the lower extremity is a valid technique for assessing peripheral nerve compression in the patient with fibromyalgia.
