Discomfort for a couple days from endoscopy biopsy?

Last night I ended up going to the ER cause I thought for sure I was having heart symptoms and a possible return of pericarditis which I had years ago. But it turned out the relevant tests all looked good across the board.

Then I put two and two together that maybe my discomforts could be linked to the endoscopy I had last week that maybe it hadn't fully healed yet.

Anyone ever experience something like that after an endoscopy with a biopsy?
