Hi all!I have been diagnosed with FM and CFS for about a year now. Prior to the FM diagnosis I was diagnosed with a B12 deficiency. Prior to that I was diagnosed with IBS. The question is does one lead to the other? There is no known cause for my B12 problem, but the docs say I will have to have injections for the rest of my life. Just a few weeks off the shots (currently I get one every other week) and I become a blithering idiot with no memory, no cognitive thinking skills, tingling in my arms and legs and a burning sensation in my mouth. I don't know what symptoms come from what syndrome anymore...they all overlap into one another. Anybody else with this combo?
