Hi I really need your advice / opinions. I have got to have a colonoscopy for a routine check up as they found a pollip 3 years ago. I didn't have any pain at all and they found no traces at all of endo . (They found that on a MRI). I have now been told that is severe endo and it has penetrated the bowl wall. The really question is will this make the procedure really painful . The hospital says need to attempt the procedure due to risk of more pollips.
