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.
Mostly, the part of the body the allergen touches affects what symptoms you develop. 1  Allergens that you breathe in often cause a stuffy nose, itchy nose and throat, mucus, cough, and wheezing.  Allergens that touch the eyes may cause itchy, watery, red, swollen eyes.
