Vasomotor rhinitis is a condition characterized by inflammation of the nasal tissues, leading to symptoms like sneezing, nasal congestion, runny nose, or postnasal drip. Unlike allergic rhinitis, vasomotor rhinitis does not respond to identifiable allergens. Instead, their complaints relate largely to airborne irritants, extremes of temperature and humidity changes, pregnancy, stages of the menstrual cycle, and emotional factors. Stimulation of vasomotor control causes a change in the diameter of the blood vessels supplying the nose.
