I went to a GERD specialist earlier this week. Since my ph as normal on my probe testing. He wants to to a Bravo ph monitor. It's the wireless device that goes deeper into my esophagous, that will monitor my ph for 48 hours. He doesn't think it's GERD. There is a very small amount of ppl that the gerd medicine doesn't work for. He believes it may be my gallbladder.
