Sciatica results when your sciatic nerve gets pinched in your lower back. The pain is typically felt as originating in your buttock, radiating down your thigh.Stretching exercises can help reduce sciatic pain. Your sciatic nerve runs through your piriformis, a muscle located deep in your glutes. If the piriformis gets too tight, it can impinge the sciatic nerve, causing pain, tingling, and numbness in your leg. Sometimes, stretching your piriformis may be enough to reduce the pain.
