Then, the next day is started to itch and
turned red. And
looked like the pictures
of a herpes blister. At first, my thought was that it was too many weeks out to be a primary HSV2 outbreak. Plus, it was only one, and it didn't have all of the prodrome symptoms. Now, I do have oral HSV1, and in fact, noticing this bump just happened to coincide with one of my cold sore outbreaks.
