Most of us think of an itchy skin rash, hives, swelling or sneezing as an allergy. It is a hypersensitivity of the body to foreign substances (allergens) when it comes into contact with them again. The response is usually the production of antibodies that try to defend the host. A cascade of defensive reactions is triggered, manifesting a wide range of symptoms. Is the same thing happening with the lesser-known "cold allergy"?
