sensation and strength to the leg
sciatica, characterized by pain radiating into one or both buttocks and descending the back of the leg, results from compression of the sciatic nerve at the base of the spine or compression of the spinal roots that contribute to the sciatic nerve. this nerve (one for each side of the lower body) is the longest in the peripheral nervous system, extending through the buttocks and down as far as the foot. this pain can occur along its entire length.
symptoms — Pain radiating through your buttock, down the back of the thigh and leg, often to the foot. The pain can be sharp or dull, shooting or burning, intermittent or continuous. It usually affects just one side of the body. Coughing, sneezing, bending or lifting may make it worse. In some cases, numbness and weakness of the affected area.
causes — Pressure on a sciatic nerve may be due to poor posture, muscle strain, pregnancy, being overweight, wearing high heels or sleeping on a too-soft mattress. It can also result from a slipped disc or inflammation of the sciatic nerve, in some cases caused by osteoarthritis.
