I feel for you Bunny I too was six months before my Doctor took much notice of my condition....I had lost twenty pounds looked like heck and my husband was taking me every week to see him.....he still insisted that there was nothing wrong with me.....I think I have to explain that he thought in the first place that it was my heart and I went through all the tests for that ....at that time blood was drawn and didn't show anything wrong....so the Doctor would tell me that there was nothing wrong with me......I got so week that he took more blood ....phoned me that evening to tell me I hadn't been imanaging this and there was something wrong......I collapsed completely three days after and had to be taken into hospital.....
That was ten years ago and I have been attending OHSU ever since....so have faith I think you will be looked after once someone takes you seriously....keep talking to the Mayo Clinic it helps.....Beryl
