Allergies are an abnormal immune reaction by the body to everyday substances.
Allergic skin reactions can be confused with other type of dermatitis. Special skin tests may be required to determine the type of dermatitis present. Proper diagnosis is important for proper treatment. Allergies can occur at any age, but the most common age when allergies begin is between 2 and 5 years. Allergic problems tend to be inherited.
