Most cysts don't cause any symptoms and go away on their own. A large ovarian cyst can cause abdominal discomfort. If a large cyst presses on your bladder, you may feel the need to urinate more frequently because bladder capacity is reduced.

The symptoms of ovarian cysts, if present, may include:

  • Menstrual irregularities
  • Pelvic pain — a constant or intermittent dull ache that may radiate to your lower back and thighs
  • Pelvic pain shortly before your period begins or just before it ends
  • Pelvic pain during intercourse (dyspareunia)
  • Pain during bowel movements or pressure on your bowels
  • Nausea, vomiting or breast tenderness similar to that experienced during pregnancy
  • Fullness or heaviness in your abdomen
  • Pressure on your rectum or bladder that causes a need to urinate more frequently or difficulty emptying your bladder completely

When to see a doctor

Seek immediate medical attention if you have:

  • Sudden, severe abdominal or pelvic pain
  • Pain accompanied by fever or vomiting

These signs and symptoms — or those of shock, such as cold, clammy skin, rapid breathing, and lightheadedness or weakness — indicate an emergency and mean that you need to see a doctor right away.
