It is normal for women to develop a small blister-like growth filled with fluid or semisolid tissue either inside the ovary or on its surface. This fluid-filled space is called a cyst. There are many causes for cysts on the ovary. Here are some signs and symptoms that you may have an ovarian cyst:
Bloating, swelling in the lower abdomen.
Painful bowel movement.
Unusually heavy or light menstrual cycle.
Pain during sex.
Difficulty emptying your bladder.
Pain from the pelvis that spreads to the lower back or thighs.
