<Li> A positive Tinel's sign </Li> <P> Tinel's sign is a tingling electric shock sensation that occurs when you tap over an affected nerve . The sensation usually travels into the foot but can also travel up the inner leg as well . </P> <P> It is difficult to determine the exact cause of Tarsal Tunnel Syndrome . It is important to attempt to determine the source of the problem . Treatment and the potential outcome of the treatment may depend on the cause . Anything that creates pressure in the Tarsal Tunnel can cause TTS . This would include benign tumors or cysts, bone spurs, inflammation of the tendon sheath, nerve ganglions, or swelling from a broken or sprained ankle . Varicose veins (that may or may not be visible) can also cause compression of the nerve . TTS is more common in athletes and other active people . These people put more stress on the tarsal tunnel area . Flat feet may cause an increase in pressure in the tunnel region and this can cause nerve compression . Those with lower back problems may have symptoms . Back problems with the L4, L5 and S1 regions are suspect and might suggest a "Double Crush" issue: one "crush" (nerve pinch or entrapment) in the lower back, and the second in the tunnel area . In some cases, TTS can simply be idiopathic . </P> <P> Rheumatoid Arthritis has also been associated with TTS . </P>
