For about a month or so I have been dealing with a numbness on my upper lip along with it the area turned a darker brown (not that noticeable) and lately it has become a bit flaky. I don't know what it means I assume it deals around herpes but no one I shared things with has any of my symptoms. Every time it does flare up I am drinking with people so I have noticed. Right now I am using cold sore cream and it was working at first until now that the area has started to flake. It does not hurt just a numbing bothering feeling that I feel is different on one side of the lip compared to the other. I am 21 years old, sexually active with one partner for the last 2 years.
