Mia ended up having marsupialization done after she had 15 Bartholin's cysts but says it "didn't really stop them from happening." ...

She explains that a Bartholin’s cyst will occur when the duct of Bartholin’s gland becomes blocked, so it is unable to drain naturally, and fluid accumulates inside it.

The Bartholin's glands, which are located on both sides of the vaginal opening, secrete fluid which helps to lubricate the vagina. When they are normal they are very small and cannot be felt.
