What is fibromyalgia really? What do fibromyalgia, chronic fatigue syndrome,chronic pain, headaches, pelvic/menstrual pain and dysfunction, and PMS have in common? These are simply different labels of a common denominator, unrecognized myofascial restrictions. Myofascial restrictions do not show up in all of the standard tests that are now performed, nor have most health professionals been taught how to recognize them.
