As I mentioned to the other person, there are MANY foods that people can be allergic to - in addition to milk. Yellow cheese gives me migraines. Get a book on allergies - There is one book called, "ALLERGIES, DISEASE IN DISGUISE." Many health problems are caused by all kinds of allergies. During the summer my feet swell and burn up, it is called "unknown edema." Doctors call it that because they don't know what else. I suspect it is another allergy I haven't discovered yet.
