Ask UK

Ooooh, buddy, you got any new smoochin partners lately? Or share a drink with someone new? I'm no doc but ya might have gotten one of the most common STDs on the earth, oral herpes.

It's fairly manageable, my boyfriend has it and I don't, (and we've been kissing on and off for like a decade and a half) you just gotta be really careful about when you have sores and make sure not to kiss anyone or share drinks until the scabs FULLY heal.

Edit: I might be wrong, though. I usually see herpes manifest as cold sores (ya might call those ulcers in the UK, i dunno), not a pus-filled zit. But, and sorry to say, ya might wanna ask a doctor about it.

It's called Herpes or HPV. There's two types, one below and one above.

The one above can pop up on your lips and even inside your nose (yeah, imagine that). It usually happens when you have a weakened immune system, so they can be considered a warning that you're more susceptible to every kind of infection.

Congratulations though. You are now part of the 70% + of the population carrying the virus. Yay.

Don’t tell me to see a doctor about a lip zit!

Go and see a doctor, I doubt it's a "lip zit".
