Suggest Treatment For Pain In The Lower Abdominal Area

I am having pain in my lower left side in the ovary area. The pain comes from my lower left back and runs down the the right area. CT Scan showed no kidney stones or no problems in the colon. One Dr. Thought I had urinary infection an gave me sulfur drugs. I told my primary Dr. I felt the same as when I had diverticulitis. She gave me Metronidazole and ciprofloxacin to take. I am finished with the medicine an am still having pain. This feels like there is really something wrong on the inside. Can you give me ant information? Sharon Solscheid Grandview Missouri
