I have gotten a pimple and or cold sore in same place three times over the last year, under my nose in the middle of my lip. I've never gotten it before this past year. I have a mustache with thick hair but now it seems to be coming up more and more. The pimple area is usually or sensitive. It pops within a day or two within development. Immediately after it pops its bloody. Then it slowly goes down while healing. There is some clear crust on it that usually flakes away if its touched after its been popped but there isnt any pain. Could this be a pimple or a cold sore?
