Why It ReturnsWhat's Actually Causing Your Sciatica
The sciatic nerve is the longest nerve in the body. It runs from the lower spine through the glute, down the back of the leg, and into the foot. When something compresses or irritates it (a disc, a tight piriformis, restricted fascia, or a nerve that has lost its ability to move freely through the surrounding tissue) you feel it as burning, shooting pain, numbness, or tingling anywhere along that path.
Most sciatica treatment focuses on the disc or the vertebral level where the nerve exits the spine. That is often the right starting point. But the nerve does not stop there. It travels through layers of muscle and connective tissue the entire length of your leg, and any of those layers can become a site of mechanical tension. If that tension is never addressed, the pain keeps returning even after the disc heals.
This is what most patients have never been told. The nerve itself needs to be able to move. When the surrounding fascia restricts it, or when the nerve develops what clinicians call neural tension, a state where it is pulled taut and cannot glide normally, no amount of stretching or strengthening resolves it. The restriction has to be released directly.
