Lower back and radiating leg pain
You've had low back pain for some time. But now you're having leg pain and a pins and needles feeling that runs through your buttock area and down your leg.
Your doctor says this may be sciatica (sie-AT-ih-kuh). Sciatica results from pressure on the nerve roots that come from the spinal cord. These nerves branch from the spinal cord, exit through openings called neuroforamens between the vertebral bones of the lower spinal column and then merge to form the sciatic nerve. This nerve runs from your lower back, through your buttocks and down the back of each leg.
