I was taking a shower and found I have a bump on around my vaginal area on the back side. I'm starting to get really worried. Does anybody know what it is?

A cyst? An STD? Polyp? Could be anything, but only a doctor can tell you what. Please see one ASAP.

You didn't mention what type or size this cyst was. Only someone observing this medical problem can advise you. Could be anything in the book. Hate to be vague, but this is complex. It's not the end of the world--I can tell you that through experience. But, it is difficult, and needs support.
