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.

Can't say for certain what is causing your pain, but I would suggest moist heat and maybe some gentle stretching afterwards to see if that loosens up. I think it may be reasonable to do that at least for the next few days as these things take time to go away. Of course, if it gets worse you may want to call your doctor.
Good luck, gentle hugs,
Leo
