Vasomotor rhinitis.

Rhinitis is characterized by nasal discharge, congestion, blockage and sneezing. These symptoms can have a variety of aetiologies, including allergic, non-allergic or infective causes. This article focuses on the diagnosis and management of patients with non-allergic non-infective rhinitis, but clearly, there are overlaps with the management of rhinitis due to other causes. Non-allergic rhinitis is very common; it is estimated to affect almost one in four adults, particularly elderly patients. [ABSTRACT FROM AUTHOR]
