Cold Sore(?)

As we know, when it comes to me trying to figure things out health wise I'm really not good at it at all. DH keeps getting what looks like pimples but they really could be cold sores and I can't tell for the life of me. No matter what I've read the whole thing throws me off when I see herpes simplex because that term just turns me off right away even thought it's not THAT. LOL! I guess it's the 10 year old in me that giggles at "dirty" words or something. I don't know what it is but it doesn't SEEM like it because they don't actually hurt but who knows. I'm glad I never said I wanted to be a doctor when I grew up. LOL
