Swollen Ear Canal: Common Causes, Symptoms and More

Allergic Reaction

An allergy occurs when the immune system releases histamine and antibodies to fight a nontoxic thing as if it threatened your health. Some people may have allergic reactions to certain hair products, such as conditioner or shampoo. This results in discomfort and swelling inside their ear. In many cases, symptoms of ear allergies are triggered by environmental or seasonal allergens. You can reduce the risk by avoiding these triggers. For medical treatments, your doctor would prescribe corticosteroid medications or antihistamines to provide short-term relief from symptoms. [4]
