A fluoroscopic guided piriformis injection is a procedure for relieving pain caused by piriformis syndrome. Piriformis syndrome occurs when the sciatic nerve becomes pinched by contractions of an inflamed piriformis muscle in the buttocks. During a fluoroscopic guided piriformis injection procedure, a combination of anesthetic and steroid medication is injected into the piriformis muscle.The medication bathes the muscle, reducing inflammation and relieving pressure on the sciatic nerve. This frees the sciatic nerve from compression and alleviates pain.
