I went out drinking and got very very drunk and woke up the next morning and had a swollen vagina inside. I can't stop thinking about it and am very worried. It had stopped being swollen by the end of the day but still can't stop thinking about it. Help

How drunk? Unprotected sex? Something else? Multiple partners?

I trust you are on some form of birth control.

Very very drunk I would have remembered having sex but I know I would not of cheated on my partner.

Then I can't imagine what would cause vaginal swelling. If you think it's an infection of some sort, make an appointment with your Doctor.
