my vagina is irritating the shit out of me

So today I took a mirror and looked at my vagina and kinda in the inside there were like bumps. So I did some research and I'm praying it's not a sti or std. but Tonight I'm going to the hospital because I can't take it anymore.

I don't think it's the pads because it's
