Fibromyalgia - Exams and Tests

There are no specific tests that can confirm a diagnosis of fibromyalgia. You will likely have lab tests to make sure that you don't have another condition causing your symptoms. Your doctor will also ask questions about your medical history and do a physical exam.

Doctors use a set of criteria to diagnose fibromyalgia. Your doctor will look for:

Widespread pain that has been present for at least 3 months. Pain is considered to be widespread if it is above and below your waist and on the right and left sides of your body.
Pain and tenderness at 11 or more of 18 specific spots. The pain usually occurs only when the areas are pressed. Experts call these tender points . But you may also hear them called trigger points. (Some people may have fewer than 11 tender points but still may have fibromyalgia.)

A person may not meet these criteria but may still have fibromyalgia. That is why diagnosis can be so difficult.
