I did go to see a breathing Dr. and he told me he saw something on the chest x-ray, but not to worry about it. That was four years ago. I haven't had a chest x-ray since then. I have tried Tecta, Lansoprazole and another one whose name I can't remember. So I have been on 3 different PPI's and they haven't helped me really. What else can I do now? Thanks for your advice.
