<human>: I was out drinking with friends last night and somehow I end up getting offered £70 to strawpedo the rest of a bottle of malt vinegar. I drink about 2 gulps before stopping. 

The rest of the night I had a pretty bad headache, felt kind of nauseous and developed a sore throat. I googled it this morning to read someone had drank only 1 tbsp and got 2nd degree caustic burns in their throat, i'm hoping that didn't happen to me but would I be able to feel the burn in my oesophagus if there was one? I'm alright with the sore throat but I guess if there's a burn I should go see someone.

<bot>: Drank some vinegar last night, found I could get 2nd degree caustic burn - would I feel it or not?
