Muscles may become damaged and painful. In some instances there is an area of the muscle which is in spasm and it is choking off its own blood supply, which increases pain. The injection of local anesthetic into the area of pain and tenderness (trigger point) can relax the muscle and allow it to heal. This therapy is best used with a rehabilitative approach including strengthening and stretching of the musculature.
For more information about trigger point injections, call the Interventional Pain Clinic, in Seattle, at (206) 223-7582.
