Ovarian cysts are fluid-filled sacs or pockets in an ovary or on its surface. Women have two ovaries — each about the size and shape of an almond — on each side of the uterus. Eggs (ova), which develop and mature in the ovaries, are released in monthly cycles during the childbearing years.
Most cysts don’t cause symptoms and go away on their own. However, a large ovarian cyst can cause:
- Pelvic pain — a dull or sharp ache in the lower abdomen on the side of the cyst
- Fullness or heaviness in your abdomen
