I have this dull pain it feels like i ned to have a bile movement but when i try it's blood i had this happen before they did colon scope and gastrosc?

Bloody bowel movment: How long ago was colonoscopy? Could be diverticular bleed or hemorrhoids. Was diverticulosis or hemorrhoids noted at colonoscopy?? To prevent bleeding from that eat high fiber oats, lentils brown rice barley every day , kale avocado .Drink 2-3.5 liters water/gatordaie juice a day (a combo too much water dilutes sodium) F/U with your doctor may need another colonoscopy if persists
