Not even sure where to start.  Last year, I met an amazing individual who has become my best friend.  He's always had digestion issues, but theyve gotten especially bad over the past 6-9 months.  Hes been tested for everything under the sun from IBS, to Crohn's to Cancer.  Nothing.  We've tried altering his diet.  Some foods, like onions, for example, will, at times, seem to make it worse and at other times not so much.  The one thing that DID come up is elevated hormone levels indicating possible cancer, but, AGAIN, there has been NO cancer found.  There HAS to be something we're missing.  There have to be others out there with answers, others who have gotten past this
