Hello I was just wondering if anyone has had a hiatus hernia with a 3mm polyp before in their oesophagus.

I had an endoscopy and was advised that i had a hiatus hernia and a 3mm polyp at GOJ (not sure what that means).

They had removed the majority of the polyp and they did a biopsy and was told this was benign. 

What worries me is they have scheduled another endoscopy in 3 months time and I'm unsure why. When i spoke to my GP they advised the polyp was quite unusual but it was benign so I shouldn't have anything to worry about. But what worries me is what was unusual about it and why am I having a follow up.

I am still experiencing continuous burping as well but not sure if that's connected to the hernia. Any advise or anyone who has had something similar happen to them?
