<<Disclaimer: Verify this information before applying it to your situation.>> I am being tested in a couple of weeks for CD. I have had diarrhea on and off but my main symtom is hives. I have been through all the allergy tests and they are negative. I know you can have dermatitis herpetiformis but mine are hives, not DH. Has anyone else with CD had hives? If so, how common are hives with CD? Thank you! Dawn
