A Bartholin's cyst, also called a Bartholin's duct cyst, is a small fluid-filled sac just inside the opening of a woman's vagina.
A Bartholin's cyst is a painless fluid-filled lump near the opening of the vagina.
A Bartholin's cyst feels like a soft, painless lump near the opening of the vagina. Large cysts can cause pain when walking, sitting or during sex.
A Bartholin's cyst can happen when the tubes that help lubricate the vagina during sex become blocked.
You do not usually need to treat a Bartholin's cyst. If it's painful, soaking it in warm water, using a warm flannel and painkillers may help.
