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.
The hip joint is designed to withstand repeated motion and a fair amount of wear and tear. This ball-and-socket joint -- the body's largest -- fits together in a way that allows for fluid movement.
Whenever you use the hip (for example, by going for a run), a cushion of cartilage helps prevent friction as the hip bone moves in its socket.
Despite its durability, the hip joint isn't indestructible. With age and use, the cartilage can wear down or become damaged. Muscles and tendons in the...
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:
Injury to muscle fibers
Lack of activity (such as having a broken arm in a sling)
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, two types of trigger points can be distinguished:
An active trigger point is an area of extreme tenderness that usually lies within the skeletal muscle and which is associated with a local or regional pain.
A latent trigger point is a dormant (inactive) area that has the potential to act like a trigger point. It may cause muscle weakness or restriction of movement.
How Is Myofascial Pain Treated?
Medications such as non-steroidal anti-inflammatories, acetaminophen or opioids may be used to treat myofascial pain. Medications for sleep, depression or muscle spasm are sometimes used, as well. Non-drug treatments may include
