Pain Management: Myofascial Pain Syndrome (Muscle Pain)
Myofascial pain syndrome (MPS) is a fancy way to describe muscle pain. It refers to pain and inflammation in the body's soft tissues.
Myofascial pain is a chronic condition that affects the fascia (connective tissue that covers the muscles). Myofascial pain syndrome may involve either a single muscle or a muscle group. In some cases, the area where a person experiences the pain may not be where the myofascial pain generator is located. Experts believe that the actual site of the injury or the strain prompts the development of a trigger point that, in turn, causes pain in other areas. This situation is known as referred pain.
What causes myofascial pain?
Myofascial pain may develop from a muscle injury or from excessive strain on a particular muscle or muscle group, ligament or tendon. Other causes include:
What are the symptoms of myofascial pain?
Myofascial pain symptoms usually involve muscle pain with specific "trigger" or "tender" points. The pain can be made worse with activity or stress. In addition to the local or regional pain associated with myofascial pain syndrome, people with the disorder also can suffer from depression, fatigue and behavioral disturbances.
How is myofascial pain diagnosed?
Trigger points can be identified by pain that results when pressure is applied to an area of a person's body. In the diagnosis of myofascial pain syndrome, four types of trigger points can be distinguished:
How is myofascial pain treated?
In some chronic cases of myofascial pain, combinations of physical therapy, trigger point injections, and massage are needed. In select cases, medication is used to treat other conditions that often occur with myofascial pain, such as insomnia and depression.
