if you can get the valtrex that'll clear it right up within a day or so and can be used as a preventative. if you don't/can't go that route, then there is an OTC topical treatment called ZILACTIN. it comes in liquid and gel and works wonders. start putting it on several times a day at the first sign of an outbreak. it coats the sore protecting it from bursting and spreading, and also works to dry it out and make it go away quicker. it'll cut at least a few days off of healing time.
i swear by the zilactin and keep it on hand always.
