I microwaved a hot dog yesterday, and the first piece I ate didn t seem that hot, but I swallowed it and it felt like my esophagus was on fire. It bothered me for a while last night but then it felt normal. Tonight I was dicing up a red pepper, and ate a slice of the pepper and for the last twenty minutes it is feeling close to the same as after I had eaten the microwaved hot food. Feels like I have to burp, but I can t. So now I am worried its something else, is this common after eating something too hot? And by common I mean if your eating something 24 hrs later, should or can this feeling happen?
