I recently noticed some round marks around my neck area, it's slightly raised and in a group of 3. From appearance it looks as if I had put a cigarette on my skin (the kind of round marks that would be left from it, if you understand what I mean). I tried to look at some skin disease articles but couldn't figure out what it is. I'm not sure if I need to go see a professional as I'm living in a foreign country right now. Help would be appreciated.
