Re: will it heal?
you can probably find something fairly affordable without insurance. Acyclovir has a generic equivilant that is fairly inexpensive, and you can call a couple of pharmacy's and find the lowest price. To get the script, you can probably go to a public health clinic or planned parenthood. I realize a lot of people aren't in any rush to make appts at those clinics, but it sure beats an outbreak like that! I would certainly look into it, just incase it turns out to be within your price range.
Otherwise, I second Beaker's suggestion that you make sure you are getting plenty of rest and eating a well rounded diet while you wait.
