Insist on getting copies of your tests. Some doctors feel that an ovarian cyst is harmless and won't say anything. That could be causing the issue.
Go to a different dr. I had issues the same and and finally a barium enema revealed diverticulitis. I also get concerned about the ovaries. Good luck and kee me posted
did you also have a colonoscopy? I would think something like that would have been found during that procedure but I'm unfamiliar with what diverticulitis is? I don't have pain. An occasional pain if I push on my stomach (left mid/bottom side) but everyone thinks I'm crazy. I'm am losing weight which makes my stomach look even bigger. The funny thing is that I feel the best in the morning and my lunch time (even if I haven't eaten anything but a banana for breakfast I take one bite of something and my stomach immediately expands. By the evening is when it's at it worse. Did they do all the other test that I mentioned above on you as well. What were your symptoms and what kind of dr. performs a Barium enema (GI dr).
