What is an Allergy? / Allergy Body Guide

As allergies can cause more symptoms than just a runny nose or an itchy throat and watery eyes, there are many signs to look out for when you suspect that you might be suffering from an allergy. More often than not allergy patients will also experience a feeling of a raised body temperature doing allergy attacks.
