What You Need to Know About Sciatica Sciatica symptoms occur when the large sciatic nerve is irritated or compressed in the lumbar spine. The sciatic nerve is the largest single nerve in the body and is composed of individual nerve roots that start by branching out from the spine in the lower back and combine to form the sciatic nerve..1  The sciatic nerve starts in the lower back at lumbar segment 3 (L3).he specific sciatica symptoms-the leg pain, numbness, tingling, weakness, and possibly symptoms that radiate into the foot-largely depend on where the nerve is pinched. For example, a lumbar segment 5 (L5) nerve impingement can cause weakness in extension of the big toe and potentially in the ankle.

From the lower back, the sciatic nerve follows the back of each thigh down to each foot.It connects the spine directly to the muscles in the feet and legs.This one very important nerve is responsible for delivering nerve signals to most of the lower half of the body.he Sciatic Nerve.

Sciatica Causes and Treatment The sciatic nerve is formed from the lower segments of the spinal cord; it is made up from the lumbar and sacral nerve roots from the spine. The sciatic nerve exits the lower part of the spinal cord, passes behind the hip joint, and runs down the back of the thigh. The sciatic nerve, like most other nerves, performs two basic functions: first, it sends signals to your muscles from the brain; and second, it collects sensory information from the legs and passes this back to your brain. Conditions such as sciatica that affect the nerve will alter these normal functions. The usual symptoms of sciatica include:

Sciatic nerve location The sciatic nerve. The sciatic nerve begins in the lumbar (lower back) region of the spine, specifically at the L4 and L5 levels. The nerve exits the spinal canal through two openings in the sacral (pelvic) spine, extending through the length of the legs. The sciatic nerve is the widest nerve of all the millions in the body, and it is also the longest nerve, which means it innervates more areas than any other nerve. Since the sciatic nerve begins in the lower back, but travels all the way to the toes, sciatic nerve pain can extend to the following areas:
