Rectal inflammation is always the very last to go with UC. Rectal inflammation is very, very stubborn. Keep after it and I am sure you'll heal it. It will take time and patience!

I think you're right when you speak of a stubborn inflammation. It sarted at the beginning of september with no real improvement since.
