Usually have outbreak on upper right side of lip, last winter started having them on bottom right side for the first time.. today i got a ob on the bottom left side of lip.. They are painless tiny blisters... Does the virus migrate? How after 5 years of remembrance do i have cold sores for the first time on the right side of my mouth? I'm using the Herpotherm (hotkiss) and i'll let you all know how it works out.. It totally stopped one of my obs that i could actually feel the tingling of.
