Sciatica
The sciatic nerves are the longest nerves in the body. They start in the lower spine, pass behind the hip joint and go down the buttock, down the back of the leg to the foot.
Pain from this nerve, called sciatica may be felt from the hip to the big toe. Sometimes the nerve is pinched between vertebrae or its passageways are narrowed by swelling of a sprained ligament in the area. Then it becomes irritated and tender. A disk may bulge out of place and press on the nerve. Rarely, an abscess, blood clot or growth may push on the nerve.
