Trigger point injection (TPI) may be an option in treating pain for some patients. TPI is a procedure used to treat painful areas of muscle that contain trigger points, or knots of muscle that form when muscles do not relax. Many times, such knots can be felt under the skin. Trigger points may irritate the nerves around them and cause referred pain, or pain that is felt in another part of the body.

In the TPI procedure, our providers will place a small needle into the trigger point. The injection contains a local anesthetic that sometimes includes a corticosteroid. Injections are given in our clinic and usually take just a few minutes. Several sites may be injected in one visit.
