Karl, the urgency should go away when you reach remission. It may be one of the last symptoms to ease up, but it will eventually do so.
Welcome to the site, but sorry you needed to come here - that is, sorry for your diagnosis.

Intolerant to Asacol and rectal mesalamine preparations.
On Prednisone then Entocort 2001-2006 with only short periods off.
