My doctor had me walking around my floor in the hospital the evening of the surgery. Walking and water to help with recovery. He may have some gas pains now and he will feel much better after his first bowel movement. It took me about
3 days to have that which is one of the first milestones. Getting that catheter removed would be the next one.
Each day should begin feeling better.
Good luck with the pathology report.
