question: I am a 45 yr woman with diabets and hypertension and have acid reflux and a herina in my espoghgus (sorry about spelling). I have been out of medicines for several days for acid reflux and this acid is making so sick, my stomach feels like someone has used it for a punching bag, and I have been nausea and this morning I was coughing up blood what could this be. I also had kidney stones removed last year, and I am having pain in my back as well.
