Without infection, this usually goes away on
the other hand, the Bartholin's glands are located on
each side of the vaginal opening and secrete fluid that helps lubricate the vagina. Sometimes the openings of these glands become obstructed causing fluid to back up into the gland, resulting in relatively painless swelling called a Bartholin cyst. At times, this fluid may become infected, creating a small area of pus surrounded by inflamed tissue or abscess.
