I had substantial pain after my first of 3. After the second part (removal of rectum, and j-pouch creation), it subsided after about 5 weeks.
Did you have the 2 part, or 3 part. You can look at your stoma a tell. If there is only one tube sticking out, its a 3 part. If there are 2 on top of each other, its a 2 part.
