myofascial pain syndrome
MONDO:0006862
Muscular pain in numerous body regions that can be reproduced by pressure on trigger points, localized hardenings in skeletal muscle tissue. Pain is referred to a location distant from the trigger points. A prime example is the temporomandibular joint dysfunction syndrome.

Myofascial pain syndrome
Myofascial pain syndrome (MPS), also known as chronic myofascial pain (CMP), is a syndrome characterized by chronic pain in multiple myofascial trigger points ("knots") and fascial (connective tissue) constrictions. It can appear in any body part. Symptoms of a myofascial trigger point include: focal point tenderness, reproduction of pain upon trigger point palpation, hardening of the muscle upon trigger point palpation, pseudo-weakness of the involved muscle, referred pain, 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. However, emerging evidence suggests that fascial tissue and its biomechanical and neurophysiological properties may also contribute to the development and persistence of myofascial pain. Diagnosis is based on the symptoms and possible sleep studies. Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. It is a relatively common cause of temporomandibular pain.
