Different people tend to suffer from different allergies and different causes of allergies; however most symptoms of allergic reactions are similar and inter-related.

Sometimes an allergic reaction may affect a single area while other times; it may affect different areas of the body. In fact, even the reactions different people experience from the same allergen may vary from person to person.
