You can be asymptomatic for awhile, or have mild reaction. Later on, and without a specific interval, you can have the kind of dramatic allergic reaction that you described. I know. I have had it happen twice to me, with different allergens. First, to cats (after having owned and lived with a cat for almost 5 years without symptoms). Then to bee stings. (Fortunately, never to dairy, although I'm severely LI.) I would say, your best bet is to follow aggressively with the allergist. Good luck.
