Hi I've just joined and had to reply to this post first..
I was diagnosed with FM over 6 years ago, by a chest consultant, that I was seeing as I have COPD aswell.. my chest pains were excrutiating, and had gone on for over a uear, I felt I had a brick in my chest, which would just get heavier and heavier if I moved about, it would also feel like a tight rubber band, squeezing my rib cage, and then I'd have the hot burning knives stabbing into me.. this was continuous for all that time.. untill my diagnosis and medication started.. I now know it was a massive fibro flare up, brought on by all the coughing the COPD was causing.. and the stress from that, linked to the fibromyalgia..flare ups are prone to all parts of the body,I've had them all believe me.. I've had these 'chest' flare ups since on many an occasion, if I've overdone thingsfor example.... the last was when I had a fall..that time so bad it hurt even to breathe.. I couldn't sit stand breathe talk.. the pain is undescribeable..
so yes could well be FMS hope that helps xx
