I get a coldsore every single time I have my period. And then I get it other times too. Lovely.

Is there anything to combat the frequency of it besides taking a pill every day? I use Zovirax and I mix some Abreva with it. But lately it hasn't been any help at all. Is it possible that I developed an immunity to those medications??????

I also apply nail polish remover to dry it out. I used to try to drain the liquid but that seemed to just make it angrier.

AND, another very important question.

Are they close at all to developing a cure (not treatment!!!) to this annoying affliction?
