What Is Myofascial Pain?
Myofascial pain syndrome is regional or localized fibromyalgia. Instead of being widespread, the pain and tenderness are found in a localized area of the body, the most common being the upper back, shoulders, and lower back. The muscles are very tender to any pressure, and nodules or lumps can often be felt within these muscles. The range of motion of nearby joints may also be limited.
