What's Rhinitis?

Rhinitis

Say: ry-NY-tis

Rhinitis is irritation and swelling of the lining of the nose. But you probably just call it a runny nose. You have rhinitis when you have a cold, but allergies to things like pollen from plants and trees also can get your nose running. This is called allergic rhinitis or hay fever. These allergies may make you sneeze or make your eyes water.
