HI, thanks for using healthcare magic

Allergic reactions can occur due to foods, environmental allergens, medication, chemical.
If you have already had through blood tests looking into the foods that you use then you may want to have additional testing to determine if any of the other groups of allergens are involved.

It may be best to consult an allergist for management.
