Are your strictures in the ileum? Are you passing stool? Fever, vomiting, bloating? These can be signs of an obstruction and if you have those symptoms id urge you to visit the ER.
You should definitely get to see your GI ASAP since it seems your inflammation is really bad or you may have a partial or full obstruction.
Try to call the on call service at your dr. Feel better and take it easy with liquids only.
