For years I have suffered with pains right below the sternum and always get what I think is heartburn. Every now and then I get a sour taste that comes up into my mouth, or I feel I have to get something that is stuck in my throat out and it is just white foamy phlem
You sound like me. I haven't had my gallbladder removed however I do have a hiatal hernia. I know my hernia is the cause of my problems. Not sure why your last test wouldn't show it I mean as far as I knew they didn't just go away and are only repaired via surgery. My suggestion is to find another gastro doctor as the one you saw seemed to not care much about
what you are going through.
