Piriformis syndrome is pain and numbness in your buttocks and down the back of your leg. It occurs when the piriformis muscle in the buttocks presses on the sciatic nerve. The syndrome, which affects more women than men, is uncommon.

Walking, swimming, and biking may all help reduce back pain. Start with short sessions and build up over time. If your back is hurting, try swimming, where the water supports your body. Avoid any strokes that twist your body.

Vitamin C is an antioxidant that helps protect your cells against the effects of free radicals — molecules produced when your body breaks down food or is exposed to tobacco smoke and radiation from the sun, X-rays or other sources.
