What are the Signs and Symptoms of Allergies?

We all know that anaphylactic shock from the sting of a bee or wasp is an allergic reaction that requires immediate treatment. We also know that wheezing, shortness of breath, and itching might also be symptoms of allergies, but even a runny nose, an upset stomach, cramps, or diarrhea can be signs of an allergy.

To be sure that the problem isn't just a desire to stay home from school, but a real allergy, testing is needed.
