Symptoms are the same as perennial rhinitis with allergic triggers. Diagnosis is determined from negative skin tests and a nasal smear test positive for eosinophils. Nasal polyps can be a complication of this condition. This is also known as vasomotor rhinitis. A person with this type reacts to temperature and humidity changes, smoke, odors and emotional upsets.
Symptoms are primarily nasal congestion and postnasal drip.
Diagnosis comes after negative skin tests and nasal smear negative for eosinophils. Some people develop the complication of an acute or chronic bacterial sinus infection, usually associated with blocked sinus drainage. The diagnosis of an acute or chronic sinus infection is confirmed by an abnormal sinus X-ray or CT scan. This type is associated with long-term use of decongestant nasal sprays or recreational use of cocaine. Symptoms typically are nasal congestion and postnasal drip.
