Chronic myofascial pain (CMP) is a musculoskeletal chronic pain syndrome that is nonprogressive, nondegenerative, and noninflammatory. It is characterized by pain and stiffness that is restricted to certain locations on the body. Like fibromyalgia, chronic myofascial pain is not a psychological disturbance, and neither condition is a mental illness, although chronic pain can cause anxiety and lead to depression.1-7 The American Medical Association, the World Health Organization, and the National Institutes of Health are among those who have accepted these as legitimate physical illnesses and major causes of disability.1
