This doesn't sound like Fibro to me. I've had it for over 6 years now, and have had no swelling w/ it. But, everyone is different. There are trigger points that can be checked to see if it is Fibro. I would get to your Dr. and let them know what's going on - it sounds like it could be arthritis. Osteo and other forms of arthritis cause inflamitory to the joints. What ever it is, you should have it checked out so that you can be treated for it. Good luck.
