The sciatic nerve runs from the lower back down through the buttocks and along the back of each leg. Sciatica is pain along this nerve and is a relatively common form of back pain and is usually caused by pressure on the sciatic nerve from a herniated or bulging disc. The pain from sciatica can be anything from infrequent and irritating to severe and debilitating. Usually, it affects only one side, the pain radiating through the buttock and down the leg and is often associated with a constant pain on one side of the buttocks, pain in the leg and/or buttock that may be worse when sitting , burning or tingling down the leg, weakness, numbness or difficulty moving the leg or foot or a shooting pain that makes it difficult to stand up. While sciatica can be extremely painful and uncomfortable, it is rare that permanent nerve damage (tissue damage) results. Most pain is due to inflammation and will improve within a period of time. Nerve pain is caused by a combination of pressure and inflammation on the nerve root, and treatment is centred on relieving both of these conditions.
Treatment for sciatica follows the lines of treatment for a slipped disc.
