What causes abdominal pain after colonoscopy?

I had a colonoscopy 2 days ago. The doctor removed a 7.5cm polyp (yes very large). Following the procedure I had 4 bowel movements (within 2 hours of returning home from the procedure) which were all blood. I have not had a bowel movement since. I feel that I have to go and am experiencing moderate abdominal pain. Is this normal?

Thanks for your query and an elucidate history.

when such a large polyp has been removed , you had 4 bowel movements containing blood only , this means there was a bleeding and may be still continuing or may be there is a hematoma in the wall of the colon .
All these factors together can cause pain in abdomen after colonoscopy.

You Need to get admitted for under-observation and if required a second-look colonoscopy with control of any condition which is causing the pains.
