false negative test results if the person has been taking acid blocking medications. I had been taking Protonix around the time of both tests and am wondering if I might actually have it and that's why protonix, dexilant, carafate, and zantac have failed to work. Nothing will get rid of the pain. I was told it was a small erosion compatible with gastritis and looked very treatable, but I'm losing hope.
