But, you're right usually herpes is blister like and spreads a bit. Though they usually start as just one, I think. Everyone has different experiences and it really depends on your immune system.
If it's really bothering you go to the doctor. It's better to know what it is for sure, so you can treat it earlier if it's something serious or if it's a flare up of herpes.
