The sciatic nerve begins in the lower back, extends through the buttocks and goes down the length of the leg. It is the longest nerve in the body. The pain that occurs when this nerve becomes inflamed or compressed is called sciatica.
Sciatic nerve. Sciatica refers to pain that radiates along the path of the sciatic nerve, which branches from your lower back through your hips and buttocks and down each leg. Typically, sciatica affects only one side of your body. Sciatica most commonly occurs when a herniated disk, bone spur on the spine or narrowing of the spine (spinal stenosis) compresses part of the nerve. This causes inflammation, pain and often some numbness in the affected leg.
