Hi E, although it may seem embarrassing (I know how you feel) you really need to go see the doctor if you are having symptoms. How do you know you have HPV? Treatments will vary, there is some great information if you go to the Center for Disease Control. Good luck!
Are you talking about low risk HPV which can lead to warts? If so, you need to get to a doctor so they can be treated. If you are talking high risk HPV (which can lead to cancer) then that is another issue.
