When doctors don’t have any feasible reason that defines a patient’s chronic pain and fatigue they usually settle on a patient suffering from Fibromyalgia. Eugene Shapiro, MD, Yale University says, “There are studies that show that people with certain symptoms who show up at a rheumatologist will be diagnosed with fibromyalgia, but if the same patients show up at a gastroenterologist they’ll be diagnosed as having irritable bowel syndrome.”
