31 yo, female.... I Have a sibling with colon cancer, with several recurrences. I have had 3 colonoscopies in the past 8 years. Have been diagnosed with colon polyps and endometriosis with full hysterectomy in 2007. Lately I have noticed a big change in my bowel movements. I am constipated for two or three days then pass a bm then will have diarrhea for two weeks. Lately the diarrhea has been loose flaky bm without the signs of mucus. My stomach has been gurgally and cramping. I never feel like I have completely passed everything and feel like I have to go all the time. My bladder feels full nonstop. And I have developed what I believe to be two hemiroids ( one the size of a pea and the other the size of a quarter) the hurt beyond belief!!! What do you think or suggest?
