I have literallydropped out...passed out, fainted, not sure what to call it, 4 times in the last 4 days. It happened so fast. I hit the floor like a brick. I think I blinked about 5 times when I came awake. In pain, and stunned. Thank God My sister was at home. What could cause this? Should I make an appt to see my MD asap? I do mot have any signs of a stroke. I am 68 HB, Heart Stints, Kidney Stints. I have been feeling really ill, for the last 2 wks. Thanks. Peggy
