Nasal inflammation can be caused by allergies or other conditions and irritants.

You may have more than one type of nasal inflammation. For instance, you could have nasal allergies complicated by a nonallergic nasal inflammation, nasal polyps, or a nose deformity such as a deviated septum. Only your doctor can accurately diagnose whether allergies or something else is causing your nasal symptoms. However, the chart below can help:
