Rhinitis is the inflammation of the nasal lining, which is commonly characterized by a runny or blocked nose. The nasal linings or mucous membrane often swell or become irritated due to factors pertaining to dryness. This condition is called vasomotor rhinitis. Besides swallowing problems, chronic sinusitis, and inhalants another cause of post nasal drip is rhinitis.

Other types of rhinitis include:

• Acute rhinitis
• Chronic rhinitis
• Allergic rhinitis
• Atrophic rhinitis

Most researchers believe that the following factors are responsible for vasomotor rhinitis:

• Recurring nasal inflammation

• Blocked nose due to nasal membrane swelling
• Sneezing
