Where is the sciatica nerve located and what type of pain it can cause?

The sciatic nerve runs from the lower back, through the buttocks, and down the back of each leg. It is the longest nerve in the body and can cause pain known as sciatica, which typically manifests as sharp, shooting pain, tingling, or numbness that radiates down the leg. This pain often results from compression or irritation of the nerve, commonly due to herniated discs or spinal stenosis. Sciatica pain can vary in intensity and may be accompanied by muscle weakness in the affected leg.
