I know two people who have Crohn's. I would be very surprised if you have it Mr Lurcher.. However, both people cope wonderfully with the disease..
Get a Calprotectin test done at your doctors. You shit into a tube, hand it back into reception, and then you'll know if you have Crohn's or not. Easily done. You'll know within a few days. I had to have this done to rule Crohn's out...
