You definitely need to see a gyn to rule out serious conditions (especially if you are sexually active). But, I have had simple pimples in my vaginal area and they do clear on their own in time. But, it is risky to wait on something that has a possibility of being an STD. By description, there is no way to tell the difference. You need to see your doctor. Best wishes!

I would think that pimples could be anywhere on the skin's surface, but when in doubt, go see your GYN. He could rule out a more serious condition like herpes or something else. Hope it goes away and doesn't come back, but if it does go away and then returns I would surely see a doctor. Sharon
