How is fibromyalgia diagnosed?
People with fibromyalgia often see many doctors before being diagnosed.

A doctor who knows about fibromyalgia, however, can make a diagnosis based upon two criteria:
Your doctor may try to rule out other causes of your pain and fatigue. Testing for some of these things may make sense to you. For instance, you may find it reasonable that your doctor wants to rule out rheumatoid arthritis, since that disease also causes pain. Testing for other conditions -- such as lupus, multiple sclerosis, or sleep apnea -- may make less sense to you. But fibromyalgia can mimic or even overlap many other conditions. Talk with your doctor. He or she can help you understand what each test is for and how each test is part of making a final diagnosis.
