I am undiagnosed, but my Doctor just informed me he wants to test for IBD. Everytime I eat something I break out into a lowgrade fever, I am on fire and sweat through my clothes. About 10 minutes later I get the chills..... Normally I am cold all of the time, so when this happens I can't help but notice. Does this sound particular to any one of the IBD diseases? I hate this uncertainty and waiting on Doctors to get back to me!
