I am 47, female, with history of heart disease and diabetes Type II. Have had acid reflux for a couple years, controlled fairly effectively with protonix. However, for the past 9 months it's gotten severe, daily, and symptoms are after I eat something, worse in evenings. Have had H-pylori, upper GI, endoscopy--nothing significant. Ultrasound of thyroid too. Nothing works, have tried omeprazole, famotidine, reglan, antacids, ranitidine, and others. My lower throat feels like it cramps and I can't breathe, then the blood and oxygen rushing to deal with that makes my heart start pounding. I am wondering: is there anything I can suggest to my doctors to look at next, or another drug I can try since the only thing that gives me relief is sublingual nitroglycerin and I go through 100 of those a month ? Thanks for ANY suggestions, I am desperate.
