Suzanne,

Thank you so much for your reply. I agree with you about the
pediatrician, I didn't think he took it as seriously as he should
have. When I asked him about the Epipen, he said he didn't need one.
Huh? The other pediatricians we saw were just as casual about it. We
have appts. with two other doctors coming up (the DAN doctor and an
immunologist/allergist), and I will ask them about it as well. As far
as the testing, he tested negative for 15 foods, including the
standard 8 (milk, wheat, soy, nuts, etc.) I'm wondering if it is MSG
or onion, since they are in the chips and dip he was allergic to.
Although, I cook with small amounts of onion and haven't noticed a
problem before. I'm reading the labels of everything now. The
pediatrician said that he had hives himself for a year and that some
kids just get them for no apparent reason, but I still think it is
worth looking for the reason, since this is a new problem for my son.
