Trigger point injections are an effective treatment option for pain in areas containing trigger points, or knots of muscle that form when muscles do not relax. These points can also irritate nerves around them, causing pain in other areas of the body. A needle containing a local anesthetic, and sometimes a steroid as well, is inserted into the trigger point to make it inactive and relieve pain.
The injection procedure takes just a few minutes to administer and is considered safe for most patients, with only minimal side effects. Aside from relieving pain, trigger point injections also loosen the muscles that cause the pain, helping with the rehabilitation process.
