Eczema, hives and other skin conditions are a common reaction in those who have a type of allergy called allergic contact dermatitis. It may be caused by sensitivity to hair dyes or perfumes. It can result from wearing rings made from certain metals like nickel or gold.

It is very seldom that an allergy becomes a risk to life. Admittedly, a number of folks are so sensitive to wasp venom they can die from a solitary sting, if not treated right away. Similarly, asthma can have serious effects as well, but for the majority, allergies are simply a pain in the neck. Not only do they make it difficult to focus, they also make us itch, cause runny noses and watery eyes, encourage wheezing and a catalog of other frustrating symptoms.

There is little good news associated with finding out that you are allergic. Unfortunately, all too many folks have first hand experience of allergies and allergic reactions. The itchy eyes, runny nose, skin rash and other assorted symptoms are uncomfortably recognizable. However a more exact medical definition of the causes of allergies may well be helpful, since it is the first step towards diagnosis along with treatment for the correct condition.
