Myofascial Pain Syndrome is common in those with Fibromyalgia.  The pain forms from muscles under the skin and are generally tender and sensitive.  Sounds a lot like the main symptom of Fibromyalgia, right?  In FMS patients, the pain can occur anywhere throughout the body or in one localized area and is commonly found in the face and jaw area.  The jaw may begin to pop when opening the mouth past a certain point.  The pop can be painful, or occur with no feeling.  The pain from Fibromyalgia can become so intense, that it stresses the muscles and is this is actually what can cause Myofascial flare ups, thus leading to..yep…more pain!
