Trigger Point Injection

Trigger points, are discrete, focal, hyperirritable spots that are painful on compression and can produce referred pain or tenderness as well as problems with muscle function. Trigger points are seen in myofascial pain syndrome, a common painful muscle disorder.

Patients often report regional persistent pain resulting in decreased range of movement of the muscle in question, which are often muscles involved in maintaining posture.

In the head and neck region, trigger point pain may manifest as tension headache, tinnitus, temporomandibular joint pain, eye symptoms or torticollis.

In the arm, the pain may mimic bursitis or tendonitis, and in the legs the pain can be a cause of limited range of movement of the knee or ankle.
