If your doc says there’s nothing left to do, you should definitely continue to seek answers. There’s always a higher authority on everything – whether a doc or grocery store complaint! If you’re interested in the Mayo Clinic, simply start by using contact info from their website. Once you have someone on the line, you can ask to be directed to the division that handles your gastro/esophogus issues. Good luck! Is IS frustrating at times. I know mine has gotten much better by going back on Aciphex and watching the acid foods. I can usually get by with a bit of cheating for something special!
