I am 32 years old and have never had a cold sore. About a week ago I was talking with this woman and I felt spit/saliva hit my lip (a few smaller droplets). Two days ago I spent the entire day snowboarding in cold, windy conditions. The following day my lower lip felt swollen and tingly/itchy. There are no visible signs of a cold sore yet, though I am concerned it could be developing. Is it possible that I caught Herpes from that woman? Is there something else that this could be? If in fact it I do have Herpes, I'm worried about transmitting it to a girlfriend either via kissing or oral sex. Is this a valid concern? Thanks...
