There are numerous types of allergic reactions. One person may have a completely different type of reaction to an allergen than another person.

Allergies are very common and the most common complaint is skin irritation. The way an individual reacts to an allergen is very unique. They may occur because of heredity, certain medical conditions, or for no reason at all.

The most severe type of allergic reaction is called anaphylaxis. This occurs when the airway swells and the person is no longer able to breath. They may also go into shock. This can be life threatening. Approximately 500 people die each year from anaphylaxis. These severe allergic reactions are caused by many different things including penicillin and insect bites.

Some of the more minor allergic reactions include skin irritation. For example, skin may become red and itchy. The nose may also become stuffy or runny and the eyes may become itchy or watery as well.

Allergic reactions can range from the slightest irritation, whether on the skin or in the stomach, esophagus, etc., all the way to violent and horrible death, all of it depending on the person, the severity of the allergy, and the specific allergen involved.

In some cases, like severe peanut allergies, what most of us consider a pretty regular food can send a child into seizures and even kill them.  This can occur simply because of the smell of the particular allergen.

The same thing is true of bee stings and other allergens, for some there are minor reactions, for others, very severe.
