Help please

Okay so I had sex right and all night my lips have been stinging and I put it down to the vodka we was drinking, flashforward to after sex I clean myself up in the bathroom and notice my lips are red raw… I’ve not had a cold sore before I’m im 99% sure I’ve not been in contact with anyone that has one currently, my lips are red and stinging and kinda looks like a layer of my lip skin has been stripped but that stinging goes away when I use lip balm, im kinda freaking out help LOL?!?!?
