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.
Allergies affect millions of people in the United States. Besides a sore throat, they commonly cause fatigue, a runny nose, post-nasal drip and itchy eyes and ears. Allergies are caused by many things, including pollen, grass, mold, dust and pet dander. Allergies are often treated by a class of medications called antihistamines.
