Women often have small, painless cysts that go away on their own (inclusion cysts). But, if you have sac-like bumps or lumps around the vagina or vulva, you may have epidermal cysts. These are usually painless, especially when they're small. Vaginal cysts can be caused by trauma, surgery, childbirth, or unknown causes.

You should monitor cysts since they can become painful and irritating, especially if they become infected.
