I don't know but I am interested too!!! Although I am undiagnosed and doctors cannot figure out what the heck is wrong with me, I have all the classic Crohn's symptoms and have tried several meds, which all made me worse... not better, and had terrible side effects for me which were worse than the symptoms themselves. I am at the end of my rope here, and just wish I could get a diagnosis! I have experimented with MMJ and for me it is the difference between being almost normal vs. being a complete shut-in!
