I have fibromyalgia and it sounds really familiar. I don't always experience pain and/or tenderness in all or many areas at the same time, either. When I do that's a bad day for me, today is one. I woke up feeling like a huge hand is pressing on the middle of my back where my bra back is and had to take a Tramadol. It's wearing off and the pain is still there, another sign of a bad day.
If you continue to experience pain or other symptoms I sure would address it again with your primary physician.

~ Just read your SWH, if you don't know already - because your mom has fibromyalgia and CF you are more at risk tor developing them or other auto-immune disorders. Sorry, but it's a fact. Mention this when you go for answers.
