My hubby has had the ph probe test , the manometry test and an endoscopy. This was all last year , and it found severe reflux , regurg and a small hiatal hernia. Anyway none of the meds have helped so now where are going back to the doc. What other tests are there ?? I have heard of the barium swallow test But don't know if they do that test or not. He had a ultrasound and hidascan of the gallbladder and they were all fine. Also does anyone else have stomach pain plus the bloating and the constant burping right after they eat???
