Hi...I am at home trying to get pain relief and find friends on this site. I am so sorry to hear how difficult your life has become due to the physical emergencies you are having suddenly in your life now. I would've immed suspected heart as I just saw a piece oh World News w Diane Sawyer...women and heart attks being pretty much exactly what you describe in your symptoms.Maybe you should see other docs. Have a stress test or just get several diff opinions. Hope to hear if you find out what it is.
