My husband has been diagnosed with celiac decease last December and has been on a strict diet ever since. He has also suffered from itchy skin for quite some years. It is affecting mostly the lower legs and scalp. It does not show as a rash but seems to have little bumps under the skin. He is using moisturizing creams on the legs and betaderm on the scalp. That helps a little, but lately it is getting so bad, that it will wake him up at night. Could this be related to celiac decease? Is there maybe some vitamins or minerals that he is missing?
