I've talked to scores of people with FMS, and one thing that seems certain is that the symptoms can vary considerably from person to person. Some complain of severe joint pain. I myself have soreness only in the muscles and occasionally the ligaments. The most important factor in determining FMS are the trigger points. If you have those, chances are very great that you have FMS.
Several times I have run into situations with doctors where they will describe you as having fibro-like symptoms, but deny that you have the illness itself. It seems quite of few of them think of FMS symptoms as just a type of rection that can occur from various illnesses, like fever or nausea does. These docs don't seem to believe that fibro exists as a primary illness.
I hope you manage to get your symptoms under control, Trix!
