Rhinitis is inflammation of the mucous membrane of the nose, caused by a viral infection (e.g., the common cold) or by an allergic reaction (e.g., hay fever). Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis.
Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain.
Allergic rhinitis is a diagnosis associated with a group of symptoms affecting the nose. These symptoms occur when you breathe in or eat something you are allergic to. You may be prescribed medicine to treat allergic rhinitis. The medicine your doctor prescribes depends on your symptoms and how severe they are.
Antihistamines and nasal corticosteroid sprays are the most effective treatments for allergic rhinitis. Allergy shots (immunotherapy) are sometimes recommended if you cannot avoid the pollen and your symptoms are hard to control.
Non-Allergic Rhinitis is not caused by an infection or allergy. The exact cause is unknown, but symptoms are typically triggered by something that irritates the nose.
Septal Deviation can also cause rhinitis. It occurs when a portion of the cartilage or bony septum protrudes into the nasal airway, causing an obstruction.
