I never had typical symptoms, doctors took ages to work out what was wrong with me because of my symptoms. I never had that much irregularity when going to the toilet, what I did have though was vomiting and lots of it. I would almost constantly feel sick and could never keep any food down. I had a few mouth ulcers, used to get joint pain really bad, especially in my knees, used to hurt to walk! Can't recall if i had any other unusual symptoms or if the rest were by the book. I will let you know if i think of anything that could be of use. Hope you get on the road to recovery soon pal.
Certainly sounds like you have Crohn's, they will probably chuck you on some pred to get you back in the game. Then see how you are.
