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.
1 The immune system is your body's defense system. In allergic reactions, however, it is responding to a false alarm. 2  Pollens and mold spores can cause seasonal allergies.  Allergies from pollens and molds can cause runny and blocked noses, sneezing, nose and eye itching, runny and red eyes rashes, or asthma.
