Herpes? Friction Blister ? Yeast Infection Sores?

A few days ago i shaved down there and cut my self with an old razor , i was scratching and rubbing all the time. I have been with my boyfriend for a year and neither of us have cheated . He has no blisters but i do. They look like canker sores or yeast infection sores i have a appointment on wednesday but i just wanted to see if anyone else had this problem
