Nonallergic Rhinitis
Symptoms and Signs of Nonallergic Rhinitis
Acute rhinitis results in cough, low-grade fever, nasal congestion, rhinorrhea, and sneezing. Chronic rhinitis manifestations are similar to those of acute rhinitis, but in prolonged or severe cases, patients may also have thick, foul-smelling, mucopurulent drainage; mucosal crusting; and/or bleeding. Atrophic rhinitis results in enlargement of the nasal cavities, crust formation and malodorous bacterial colonization, nasal congestion, anosmia, and epistaxis that may be recurrent and severe. Vasomotor rhinitis results in sneezing and watery rhinorrhea. The turgescent mucous membrane varies from bright red to purple. The condition is marked by periods of remission and exacerbation.
