Chronic rhinitis is a condition in which the nasal mucosa is inflamed for 12 weeks or more, caused by many different causes. In some cases, chronic rhinitis is due to genetics and is very difficult to treat completely. However, if treated early and properly, it will help reduce uncomfortable symptoms, the number of recurrences as well as the risk of progression to dangerous complications.

Allergic rhinitis in children is a condition in which the nasal mucosa (the membrane lining the inside of the nose) becomes inflamed due to an allergic reaction to internal and external agents. When exposed to allergens, the body releases histamine, causing itching, swelling, and fluid buildup inside the nose.
