I have just read this article by Dr Martinez-Lavin a cardiologist who makes the interesting suggestion that fibro is a form of autonomic dysfunction. Anyone have thoughts on this or know of any studies or research? I am wondering if it would explain the mast cell dysfunction findings and the high incidence of heart problems with those of us with FM as a primary dx. There's some anecdotal evidence that the biggest cause of death in FM patients is sudden heart attack or stroke. THIS PAPER says more on it I have to say that this seems to make sense to me, but I wonder if that's just because I so very much would like to have an easy to grasp understanding of the what the heck is happening to me. Any thoughts?
