Question:
Hi im 19 and i found out that I have a cold sore yesterday from the doctor. I'm not sexually active and i have no partner, and my family is clean. I dont know of anyone friend that has herpes either. Small blisters just appeared out of know where on my uppper lip yesterday. I still don't know how i got it.
Is it just a normal thing or does my blood really has a virus in it? Should i go test for std? Need help thank you.

Answer:
Also i havent kissed anyone. The last person i kissed was like 5years ago. The blisters are not red. They are just clear like the blisters you get on your hand.
