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.
Histamine is responsible for most of your allergic symptoms in your respiratory system, gastrointestinal tract, skin or cardiovascular system. Among these symptoms of food allergies is swelling. While it's normally your lips, tongue and throat that swell, you can swell up anywhere when you eat a food you're allergic to.
