Trigger point injections are done for people with myofascial pain syndrome. When your muscules are chronically sensitive to touch and painful with movement, you may have inflamed areas of muscles or trigger points. Injecting the muscle with a local anesthetic/steroid may reduce the inflammation and allow better range of motion. Typically, stretching and exercise, especially with physical therapy, will assist with this process. Also may require electrical stimulation with a TENS (Transcutaneous Electrical Nerve Stimulation) unit.
