cold sores
"I contracted the disease thanks to my then-boyfriend, whose whole family, including himself, got them. I tried everything to make them go away - Carmex, Campho-Phenique (which was just ridiculous), even ice.  Nothing worked.  My then - boyfriend finally got a prescription for Denavir, which only worked once. It helped heal the cold sores, but never prevented them. Valtrex was prescribed to me and I never got them. "
