The hamstring syndrome--a new gluteal sciatica.

The condition in which pain is felt over the area at the ischial tuberosity and radiating down the back of the thigh is labelled the hamstring syndrome. The pain is typically incurred by assuming a sitting position, stretching the affected leg or/and running fast. The symptoms are caused by tight, tendinous structures of the hamstring muscle at the area of its insertion into the ischial tuberosity. Following division of these structures, complete relief is obtained.
