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 arthritis or swelling of a sprained ligament in the area, and it becomes irritated and tender. Rarely, an abscess, blood clot, or growth may push on the nerve. Yes, although low back pain often comes with it. Usually, sciatica affects only one side.
Pain often radiates down the buttock or leg.
Coughing, sneezing, and sitting make the pain worse. Your leg or foot may be numb or weak and have odd sensations in it. You may be unable to move your foot or bend your knee. For severe episodes, rest on a firm mattress or the floor for 2 or 3 days, getting up only to use the toilet. Then carefully start moving around for short periods, but don't bend, lift anything, or sit in soft chairs.
