I agree that you need to get to the doctor. Have you ever engaged in oral sex with someone that has cold sores on their mouth? If not I dont really see how you could of contracted herpes. You could have some kind of bacterial infection that isnt going away because your not getting rid of what is causing it, your laundry detergant, your shower soap.
Best thing for you to do hun is to go to the doctor and find out for sure what is going on, you will feel better trust me
