Allergic rhinitis, or hay fever, is swelling of the inside of your nose. The swelling is a reaction to allergens in the air. An allergen can be anything that causes an allergic reaction. Allergies to weeds, grass, trees, or mold often cause seasonal allergic rhinitis. Indoor dust mites, cockroaches, pet dander, or mold can also cause allergic rhinitis.
Throat swelling allergies are a common sign of anaphylaxis, a severe allergy that affects your entire body. Any allergic reaction can cause anaphylaxis, but some are more common than others, such as insect stings, certain food allergies and medications. Call 911 if you develop swelling in your throat.
