it's odd that your doctor can't tell why you are bleeding. at this point you should probably get a colonoscopy - if you have insurance it might even be free. if they gave you a cream they probably thought it was a hemorrhoid. it could also be an anal fissure farther in. or it could be a polyp. it could also be diverticulosis or diverticulitis which is what happens when your large intestines develop little pouches in the side and sometimes they bleed. my dad nearly bled to death when one of those let go but luckily they are also very treatable. he's fine by the way. a colonoscopy is going to be able to tell you a lot more. they don't make you go through it while fully awake so it's not even all that uncomfortable.
