How come after you burp, sometime you're nose hurts?

Question

I know it sounds a little weird, but you're nose kinda burns. What is the called, and why does this occur?

Answer 1

Your oral and nasal cavities are connected. So, when you burp, and if you're trying to hold it for whatever, reason, the gas is trying to escape any way it can. So, if it can get out of your mouth, it will get out the next best way - through your nose. The gas, which is probably acidic, burns the sensitive epidermis of your nose. And that is why your nose hurts sometimes when you burp.
