I have intermittent abdominal pain, but when I have it, it is severe. It usually lasts for 7 - 10 days and then goes away for about 3 weeks. I had an ultrasound and the only thing it showed was three fibroid cysts and my doctor said that they were not big enough to cause the pain. I have a history of breast cancer and had my ovaries removed about five years ago. The ultra sound also showed free pelvic fluid. My doctor has ordered a CT scan of the abdomen and pelvis. The pain is so severe that pain medication does not help. Any ideas what could be causing the pain?
