We went for the standard food allergy test a few months ago, with regard to my 13 year old daughter suffering from migraines, some of them severe. She has since cut out milk which was one of the main things that you flagged up. She has had only 2 migraines since. I was pleased with how easy the whole process was, and will be soon doing the food test myself as I suffer from rheumatoid arthritis and am convinced some foods are irritants.
