Why do I have constant pain and constipation when ulcerative colitis i

I was diagnosed with ulcerative colitis in 2016. Mayo put me on Entyvio in 2018 and I have been in remission ever since yet I suffer almost daily from abdominal pain and bloating with constipation. My doctor wants me to go back to Mayo for IBS but that is out of the question. Colace can be too hard on me at times but doctor says to take it daily as needed. Can anyone relate to any of this cycle. Thanks.
