Errr i got a bad cold sore >_<;?

My mom and I get cold sores all the time. I hate them SO much. We both use an ointment called Zovirax. You need a prescription from your doc to get it but it works great. The source I have listed below says that it won't help prevent them which is true but if you notice one or think you are about to get one put a little bit on and on average for us they last about 3 days then sometimes less. Also a little goes a long way so don't waste it! :)
