Symptoms of Allergic Rhinitis
Allergic rhinitis is an allergic inflammation of the nasal airways. Symptoms include sneezing, congestion, runny nose, itchy nose, eyes and throat, and postnasal drip. Allergic rhinitis can be triggered by exposure to pollen, dust mites, pet dander, mold spores, and certain foods.
Symptoms of Non-allergic Rhinitis
Non-allergic rhinitis is an inflammation of the nasal airways that is not caused by an allergic reaction. It can be caused by viral infections, environmental irritants such as smoke and strong odors, certain medications, and changes in temperature or humidity. Symptoms of non-allergic rhinitis include sneezing, congestion, runny nose, and postnasal drip.
Diagnosis
The best way to determine whether you have allergic or non-allergic rhinitis is to see an allergist. An allergist can perform tests to determine which allergens, if any, are triggering your symptoms. They may also order a CT scan or MRI to rule out other causes of your symptoms.
