maybe im just perinoid, but i have had two coldsores on my mouth this summer. I heard on the radio that a lot of sunexposure brings about coldsores, and i am a lifeguard, but are there any signs to how i could know if i have them or not? i get pimples around my mouth sometimes.. but i do have acne, and sometimes i wonder if its just from lip gloss or something.. HELP

If you have cold sores then you have herpes. Sun exposure can trigger outbreaks, but it's not the cause of herpes. It's really common, so don't worry too much about it. Your doc can do a blood test if you want to know for sure, and can prescribe a topical cream to help heal your outbreaks more quickly.
