Peanut allergy is common. In fact, peanuts (which technically aren’t nuts) are one of the top allergy-causing foods, producing reactions that can range from mildly irritating to severe and life threatening.
Symptoms of peanut allergy include itching, hives, sneezing, and abdominal pain. If anaphylaxis occurs, then there may be dizziness, throat swelling, shortness of breath, etc. Anaphylaxis can cause death.
