Diagnosed with crohn's last October. Currently on 3rd month of Budesonide doesn't appear to be working. Friday night was the worst ever. Watery poo and brown snake like vomit only way to describe it was like Mr Whippy ice cream only brown. Should i have gone to hospital. Lost 18 pounds in weight. Gained at least 8 by drinking plenty of fluids. Get serious back pain when i don't eat. Any ideas.
