Oh and if you meant trying wart treatment at home, don't do that to yourself. If it is warts, it probably won't work, and can cause irritation. If it isn't warts, you could make things a lot worse.

It might be warts, herpes, molluscum, infected hair follicles, etc.
If you can't get into a gp within the next day or 2, then go to an instant/urgent care center or an std clinic.
