A Trigger Point Injections (TPI) is an injection that is given directly into an active trigger point for the management of pain.  Trigger points are discrete, focal, hyper-irritable spots located in a taut band of skeletal muscle.  Trigger points produce pain locally and in a referred pattern and often accompany chronic musculoskeletal disorders.  The goal is to reduce the inflammation and associated pain to allow for increased range of motion and participation in physical activity.
