10 Causes of Itchy Ears
Cause #7: Food Allergies
Food allergies are abnormal immune responses to food. They can cause symptoms that range from mild to severe. Examples include tongue swelling, diarrhea, vomiting, hives, difficulty breathing, low blood pressure, itchy skin, and itchy ears. Symptoms usually appear within minutes to hours after exposure.
Common foods that cause allergies include peanuts, eggs, cow’s milk, fish, tree nuts, shellfish, rice, and wheat. A protein in the food is usually the causative factor as it triggers inflammatory chemicals such as histamine. Management of food allergies include having a plan if there is exposure, adrenaline, early exposure, and wearing medical alert jewelry.
