Someone told me long time ago, if you swallow the puss that is in your canker sore/ulcer, you can most likely die from from it. because of this, the ulcer has poison in it from puss.
Burping has nothing to do with ulcer. You swallow the air, while eating the food. This air comes out when you burp, usually when you drink a water after food.
Don't worry, you'll be alright.
it hurts and puss comes out
Nothing happens
You Die
you die
you die...
pain
You can get chemical burns along your throat and stomach if you swallow lye.
You burp bubbles
if you pop an ulser nothing realy happens. sometimes in your mouth you feel some kind of water coming out of your mouth. This is puss and it happens the same with an ulser. Try not to pop an ulser even if it hurts
It depends on how much you swallow. If it is a large amount, you could get diarrhea and/or vomit.
