Fibromyalgia Support Group
You're not alone in your pain. Fibromyalgia is a condition that can be difficult to diagnose and manage. If you're trying to cope with pain throughout your body, sleep problems, general fatigue, or other common fibromyalgia symptoms, you're in the right place. The community is here for you to talk about therapies and share your challenges.
TMJ comes from deep in the jaw and "might" respond to topical pain medication but I would definitely talk with your doctor about it.
Here is a site that has exercises which were the same ones that my PT did with me. I continue to do them, and from the feedback on other boards, others have gotten relief. I hope this will help. Also, a splint has been of help to me, but it doesn't work for everyone.
