Is there a way to tell if my doctor really knows anything about FMS?

Ask your doctors about trigger points, if you want to see how much they actually know about fibromyalgia. If they act confused, or if they start talking about sore points in your joints or muscles, then they don't really know the specifics of fibro. However, if they are willing to learn, point them to some good books on the subject. If they know what a trigger point is and have passed the first test, you may very well have yourself a good doctor.
