Myofascial Pain Syndrome

Myofascial pain syndrome (MPS), also known as chronic myofascial pain (CMP), is a syndrome characterized by chronic pain caused by multiple trigger points and fascial constrictions. Among the symptoms are referred pain, limited range of motion, and sleep disturbance.

Symptoms

Myofascial pain can occur in distinct, isolated areas of the body, and because any muscle or fascia may be affected, this may cause a variety of localized symptoms. More generally speaking, the muscular pain is steady, aching, and deep. Depending on the case and location the intensity can range from mild discomfort to excruciating and "lightning-like". Knots may be visible or felt beneath the skin. The pain does not resolve on its own, even after typical first-aid self-care such as ice, heat, and rest.

Causes

The precise causes of MPS are not fully documented or understood. Some systemic diseases, such as connective tissue disease, can cause MPS. Poor posture and emotional disturbance might also instigate or contribute to MPS.
