I haven't been sexually active in around 3 months, anyways this pimple looking thing popped up on my lip as you can see in the picture below ... its day 3 and it went down significantly; btw i've never had anything like this before.
It never opened up and i didn't notice any fluid inside ... could it be herpes?
I'm thinking its just a pimple or maybe a bug bite.
