Does anyone else get a lot of digestive problems with FM? I have been having trouble with my stomach for so long. have had all the tests but all come back negative. I have this feeling of a large lump in my upper abdomen and like a missed heart beat,I feel full up even eating the smallest amount of food, it is very uncomfortable, my Doctor has said that it could be mustle problems dUe to the Fibro but I run a support group for Fibromyalgia and cannot find anyone else that has it. HELP!!!!!
