<unk>  <unk> , also known as chronic<unk> <unk>  (CMP), is a<unk>  characterized by chronic<unk>  in multiple<unk>  trigger points ("knots") and fascial (connective tissue) constrictions. It can appear in any body part. Symptoms of a<unk>  trigger points include: focal point tenderness, reproduction of<unk>  upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred<unk> , and limited range of motion following approximately 5 seconds of sustained trigger point pressure. The cause is believed to be muscle tension or spasms within the affected musculature. Diagnosis is based on the symptoms and possible sleep studies. Treatment may include<unk>  medication, physical therapy, mouth guards, and occasionally benzodiazepine. It is a relatively common cause of temporomandibular<unk> .
