I have sporatic abdominal pain (left lower) (severity: moderate). been almost a year. had colonoscopy, ultrasound, gyne check, no signs, still painful?

Left lower pain: Left lower abdominal pain with a negative colonoscopy and gyn evaluation raises the suspicion of diverticular disease which is sometimes missed on colonoscopy. Has your gynecologist ruled out endometriosis as a cause? If so, consider a barium enema examination if your symptoms persist or if you have any associated bowel symptoms or episodes after eating harsh roughage(salads,nuts,raw veggies).
