Numerous things can cause a runny nose or rashes to suddenly appear on the skin but determining if these conditions are the result of an allergic reaction requires a professional diagnosis. Amongst the most common and successful methods used to test for allergies are skin tests. Allergy testing procedures inject or scratch a small quantity of the potential allergen, such as pollen extract, solution containing animal dander proteins and others under the skin.

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.
