Milk allergy is very common. It causes a variety of symptoms from splitting headaches, tinnitus, skin irritation, asthma, wheezing, breathing problems, sore throat and gastro-intestinal/stomach problems. Imagine ingesting poison ivy. The body reacts everywhere it touches. Same with milk - it's NOT lactose intolerance, it's true allergy. Allergies get worse with exposure, not better so be sure to eliminate dairy products from everything!
