I have a patch of red irritated skin that comes and goes. I had big, red, painful welts on my legs too. They're not itchy. I suspect I might be allergic to either quinoa or milk.

One of the most common symptoms of a food allergy is hives or urticaria. These are raised, red, and very itchy skin rashes. They can appear on the face and other parts of the body. This is typically seen within two hours after eating a relevant food allergen (e.g. cow milk, egg, peanut). Your rash is red and raised, but it is not itchy. This is not likely to be hives.

Your rash may not be due to a food allergy. The best advice would be to have your rash evaluated by your doctor. They can make an appropriate diagnosis. Meeting with an allergist or dermatologist could be very helpful in identifying the cause. Allergy skin testing can be useful in ruling out a food allergy. In some cases, a skin biopsy would help identify the specific cause of your skin rashes.
