Signs and symptoms:
The sciatic nerve can literally be a huge pain in the butt. It is the largest nerve in the body, which consists of a large bundle of smaller nerves that begin in the lumbar spine, travel down the buttocks, and move through the leg. Technically, sciatica is not a disease, but a group of symptoms that affect the region of the sciatic nerve. These may include back pain but there may be only hip, leg pain or even foot pain. Sometimes there is minimal pain and the patient mostly suffers from numbness or tingling, we call paresthesia. There may be leg weakness or coldness. The presentation is quite a bit variable and usually manifests on one side only.
There may be aching, stabbing or burning pains. There may be spasms, shooting pain or the leg may give out causing a fall.
