<<Disclaimer: Verify this information before applying it to your situation.>> I am NOT diagnosed celiac, however do have one of the celiac genes (DBQ2? Not sure of the order of the letters and numbers). Along w/ the rest of my family (husband blood test positive for celiac, three children who we have observed react to gluten, plus two more w/ no apparent reaction to gluten) I've been eating gf. However, a couple time over the past three or four months, I've cheated, and now I'm starting to wonder how "coincidental" some things really are. Before going gf, I'd had terrible dandruff or seborrhic (sp?)dermatitis, was prone to cold sores, and often had migraine-like headaches. Since June, I've still had the occasional headache, but the dandruff (?) has cleared up, and I've had few cold sores. BUT, the two times I've cheated, w/in a week, I've had splitting headaches, itchy scalp, and this week, a developing cold sore. (But that egg roll was really, really good!) Can anyone else relate?
