Allergies involving the nose are typically referred to as allergic rhinitis or hay fever. Symptoms of allergic rhinitis can include itching of the nose or roof of the mouth, runny or stuffy nose, and sneezing.
In addition to seasonal and perennial allergen triggers, symptoms of allergic rhinitis may also result from irritants like smoke and strong odors as well as changes in temperature and humidity. People with allergic rhinitis have inflammation in the nasal lining, which increases their sensitivity to such inhalants.
Allergic rhinitis is also associated with allergic conjunctivitis, as many people with allergic rhinitis are also prone to eye allergies. Previous studies have shown that nearly 90% of patients who report nasal symptoms actually have ocular symptoms as well. Furthermore, the nature of allergic rhinitis can also worsen symptoms of asthma for people who suffer from both conditions.
