i have not felt good for a long time now but lately I am always exhaused, my left arm is numb, it doesn't hurt, its more like pressure, and I have little black outs. I keep telling my dr. this, lately my legs and ankles, feet swell so large it feels like the skin is being torn apart, i had a mri in april, the dr. said it showed white spots, on both sides..My husband and I are very concerned. there are times i actually lose i, he actually has to follow me i have fallen passed out from a few mins to a few hrs. I had even urninated myself. What are white spots on the brain, loss of activity? I don't know what to ask or where to go, the passing out is very dangerous as i have fallen and stayed on the floor for longer than a hr. i nearly killed myself smoking, the mattress was on fire, I seem more concerned than the dr. my father died of cardio myopothy, but he didn't have a autotospy so i don't know if it was hereditary?
