hi I’m new to this so,

over the past year I’ve had bleeding and different kinds of bowel movements, so I’ve had a colonoscopy and everything was fine until I had the camera they couldn’t finish the procedure because I was in so much pain even on the maximum sedation. The end of it they said that there wasn’t any hemroids or growth as they could see but now I need a ct scan to have it finished so they know but they have taken 4 biopsy’s. I don’t understand  how all the symptoms are there but no clear view. Scared is all I am right now
