For last several months I been noticing that after eating Kellog's Raisin Bran Crunch cereal or drinking chocolate milk I get really itchy all over my body. Usually starts out as bowel movement then really uncomfortable itching on my hands, feet, mouth, down there. These symptoms don't occur at night when I have a full stomach. I am wondering what specifically I am developing an intolerance or allergy to? I am 33 yr old female.
