I hope you see this but I think I’m going through the same thing, i had a biopsy done on my esophagus after having some food get stuck, I’m 3 days post surgery and even when I drink water it feels like acid when it goes down from 2/3 way down on my esophagus to my stomach and pretty much everything I eat feels like a burning sensation going down. I scheduled another doc appointment but should I be worried?
