What Is Sciatica? The Real Path of Sciatic Nerve Pain Sciatica isn't just simple back pain—it's caused by irritation or compression of the longest, widest nerve in your body. Starting from your lower spine (L4, L5, and S1), the sciatic nerve travels down through your buttock, thigh, knee, and all the way into your foot. Because of this extended pathway, symptoms like burning, tingling, numbness, or shooting pain can show up at any point along the leg. Understanding this anatomy helps explain why doctors ask precise questions about where your pain travels. Where do you feel your sciatica pain the most?

The largest nerve in your body might be behind that shooting pain down your leg. Meet the sciatic nerve. It runs from the hip, down the back of the thigh and lower leg, into the foot, and it is built from five spinal levels: L4, L5, S1, S2, and S3. So a herniated disc at L4 or L5 can affect those contributions. But S1 to S3 are not off the hook. A disc that herniates laterally presses on the nerve exiting at that level, while one that herniates posteriorly, straight back toward the midline, pushes into the spinal canal where the lower roots still run. Press on those and you get sciatica: shooting pain down the leg into the foot, numbness, tingling, even muscle weakness. Want anatomy like this live with our team?
