I agree, fibro can take something & make it 10x worst... You really should do what blue said. Also see if it could be gall stones. Those were painful & I remember how it was for me. But I've known other people with it that had different symptoms. My husband also gets bad stomach & back pain from kidney stones... It could be anything so please talk to your doctor & have them run tests. Not everything is fibro. Sounds like you have something going on other than fm.
