Hi. Well, truthfully, that sounds like a pimple to me. Cold sores normally make a blister and scab that is flat. You've seen people with them, I'm sure. But I know when you are looking in the mirror, it is hard to tell. Herpes simplex one is one of those things that such a huge percentage of the population has, up to 80 percent they say with many getting it in childhood, that you know, you always 'could' have that. But again, guessing pimple. I'd just clean the area really good and see if anything else ever develops. Probably won't. good luck
Yeah that's what I thought as well. I haven't shared any drinks or food with anybody or kissed anyone either, so I don't really know how I would get a cold sore. Thanks for the feedback.
