I had a pimple looking thing on the side of my mouth a few days ago and i picked it cuz i thought it was a white head. Now that i think about it it was really weird it was like a white head, but the middle of the pimple was a dark spot thing i don't know why. I have only been with one boy for the past three years he was the first kiss for me so i don't think it's herpes. I've had a cold so i don't know if that has anything to do with the herpes. It didn't feel hot or tingly and it looks like a deep cut now that i picked it. I don't know if it's an infected pimple or a herpes blister.
