Cold sore, cold sore, cold sore?

I got a cold sore about a day ago and have been using Campho-Phenique. I've used it on previous cold sores but it usually takes about a week or more to cure with this medication. It covers almost all of my upper left lip area and is extremely swollen. I have school in the next 3 days and I would like to cure it... show more I got a cold sore about a day ago and have been using Campho-Phenique.

Please recommend any cold sore remedies or gels. Thank you.
