Sciatica is the term used to describe a set of symptoms that include pain, numbness, tingling, and/or burning that travels from the low back, down the buttock, and down the back of the thigh and leg, sometimes extending into the foot. There can be weakness in the leg or foot as well.


Sciatica is most commonly caused by the compression of a nerve in the lumbar spine by a disc herniation. It most commonly affects only one side. Diabetes is a common cause of peripheral neuropathy. Less commonly, stenosis or narrowing of the spinal canal can cause sciatica. Other causes of leg pain, numbness, tingling, burning, and weakness include peripheral neuropathy, vascular disease, and piriformis syndrome.
