Yes, I know because I have it. It is spelled Fibromyalgia. You will have tender points and possibly trigger points on your body that will hurt.
Here is something for you to look at:
The American College of Rheumatology bases the diagnosis of FM upon two major criteria: 1) widespread, diffuse pain lasting at least three months and 2) a minimum of 11 (out of 18 possible) specified tender points throughout the body. This is the strict definition for being included in a clinical study of fibromyalgia, but tender points may change from time to time, and may worsen or get better in the cyclical way that this syndrome seems to work.
These tender points will hurt when pressed, but the pressure will not cause pain in any other part of the body. The physician applies a standardized amount of pressure, about 4 kg (enough to turn the thumbnail white). Remember, a tender point has to be painful at palpation, not just "tender." When pressed, these areas tend to feel like bruises in various stages of healing.

Also, a tender point is different from what you may know as a trigger point. Tender points hurt, trigger points hurt and refer pain to other body parts. Trigger points cause myofascial pain syndrome, which often coexists with fibromyalgia, but can be treated with massage, physical therapy, or gentle stretching. When muscles feel hard and pressing on them causes a response elsewhere in the body, or even nausea, trigger points are responsible. Tender points are caused by an unknown mechanism, and their severity is often cyclic. Tender points do not generally respond to physical therapy, often becoming more painful with pressure.
