Thanks to both of you for the honest replies. I have a follow up with my primary care doc this week. At this point I don't think any number of colonoscopies is going to yield any useful information. What I know is that both bleeds seem to show bright red, indicating a lower bowel issue rather than small intestine. I'd like to ask him about at least consulting with a GI to see if a CT angiogram could point to a general location of bleeding. Maybe there's a small chance that there's trace amount of blood continuously leaking from a single location. I dunno. I feel like I'm grasping a straws but don't want to sit around waiting for the next episode to send me back to the ER.
