Sciatica refers to back pain caused by a problem with the sciatic nerve. This is a large nerve that runs from the lower back down the back of each leg. When something injures or puts pressure on the sciatic nerve, it can cause pain in the lower back that spreads to the hip, buttocks, and leg. Up to 90% of people recover from sciatica without surgery. The kings park chiropractic clinic chiropractor near me said, although the pain associated with sciatica can be severe, most cases clear up with treatment in a few weeks,such as chiropractic care, acupuncture. People who have severe sciatica and serious leg weakness or bowel or bladder changes might need surgery.
