1. Yes. it can be a pimple and doesn't have to be HSV.
2. I doubt it.
3. It's possible but not likely of there's no visible blister.
4. Most people get a first attack that is mild, reflecting antibodies already present (in other words, the first exposure didn't produce fever, swollen glands, etc.)
If I were you, I'd forget about herpes of the lip. If you get a cold sore, you can worry about it then. Show a doctor your pimple just to be sure, then just leave it alone.
Best.

I also have a similar problem, but the pimple is on my lower lip. It doesn't pop and I had it for over a year. It hasn't gone away. I am a smoker and was wondering could it be just callus from that because the bump is on the part of my lip wherre I hold my ciggarette. Thanks.
