Trigger Point Injection Procedure

A trigger point injection procedure is a procedure performed to relieve tenderness or as treatment for pain. A trigger point is a knot or tight band of muscle that can be felt under the skin and forms when a muscle fails to relax. To help with the pain, a trigger point injection procedure is performed, which involves a small amount of local anesthetic, with or without steroid, that is injected into a trigger point.
