So Im an idiot and I just realized that this was posted almost a year ago, and since Im looking for answers to my problems, did you find out what caused this breakout? Because that might help me out
You didnt mention if your lip became red when it first broke out on the edge, I assume it might have been. I also had a similar break out at the edge of my lips that was itchy, dry, and red that ran along the edge of my lip. Like badly chapped. I'm also concerned that I got oral herpes and the doc said that it doesnt seem like a typical case, mostly because mine has lasted 2 months, with various symptoms. He gave me a topical steriod cream which cleared it up in a couple days but I'm still not convinced that its not herpes. It could be nerves and if your playing with it constantly, it wont help the dryness. Does your tingly sensations last all the time or does it come and go? As far as I know oral herpes show blisters. How long have these symptoms been showing? It could also be from tanning, that dries out your lips and it could be irritating your skin. If you find out anything, please let me know since Im still looking for answers too.
Does it sound like oral herpes?
this could be many things. I'd stop using the neosporin lip treatment just in case it's a reaction to that. If it's still this bad monday, see your provider.
