A member asked:
My bestfriend's bf gets lip blisters ever since he was a kid. he got them last in 2012 due to sun exposure, this time after a fever. is it contagious?
A doctor has provided 1 answer
Cold blisters: Herpesviruses at the edge of the lip are contagious, so much so that most people your age are already infected. Stress, illness and sun exposure can cause a new breakout.
