I have had a sore throat for a year now. Doctors think it is acid reflux. Have had endoscopy, gastric emptying test, cat scan. All came out negative. I have tried all otc drugs, Prilosec, zantac. They do not work. I am now trying Nexium but that seems to be making sore throat worse and I am coughing more. On top of that I am dealing with osteoporosis. I am only 43 years old. What do you suggest? Please help.
