<<Disclaimer: Verify this information before applying it to your situation.>> I have struggled with hives over the years and can get them from simply eating the same foods daily for several days. I am not a diagnosed CD. My GI doc is trying to rule out other problems first. I have found that one way to reduce the length of the breakout (I get them in the center of my chest and sometimes down my back and legs) is to take a gram of Vitamin C. Less than that has little effect in my experience. Robert Peterson Reno, NV
