Myofacial pain can be either regional, limited to a specific area, or systemic, widespread. It is not synonymous with fibromyalgia which can have a host of other symptom features. Myofacial pain can originate from an injury, such as a strained or a pulled muscle, but can also result from physical inactivity, obesity and general lack of physical conditioning.
Initial evaluation and treatment will focus on minimizing pain and rule out ongoing sources of muscle injury. Once the injury has been given enough time to heal, the next part will be to get the patient into better shape, and this includes learning better posture, body mechanic, and muscle conditioning exercises.
Physical therapy, especially tissue mobilization and deep tissue work along with trigger point injections are effective treatments.
