Is the blister on your vulva? Like in between your lips or by your clit? Also what exactly does the blister look like? Herpes sores are like this:
Start as a pimple like red bump, its itchy and sore
Bump pops and becomes an open lesion
Puss and blood come out
It forms a white film (like a white head)
The film turns into a scab
The sore heals after about a week
I have never had a sore on my upper pubic region (like where the hair line is) IS this where it is?
