So I have this red patch of skin under my lower lip. I have absolutely no idea what it is and I've never had it before.
History: A few weeks ago, I had a cold sore on my lower lip. It was very small and only took a few days to heal(I found it early and immediately put on cold sore medicine --Zilactin and I iced it). After it healed, I saw a few small dots right under it. I thought maybe the cold sore had spread, so I iced it down again and put more Zilactin on it. It didn't really help. Initially, I thought it was just a rash because when I had the cold sore, i was licking and biting my lips a lot.
Fast forward to now, it developed into a red patch. I'm very sure it's not a cold sore. It isn't painful at all, but it does get itchy sometimes. I've tried everything from icing it to zilactin to neosporin, to aloevera, to hydro cortisol. Nothing has been working.
Any suggestions as to what it is and how to treat it? At this point, I'm paranoid that it might be some kind of STD.
