The differences between chronic rhinitis and allergic rhinitis are quite significant. Firstly, we need to consider the causes of the diseases. Allergic rhinitis is mainly caused by the body's own immune response, primarily due to allergens the body encounters externally, which trigger this immune response. Chronic rhinitis, on the other hand, is primarily associated with local inflammation of the nasal mucosa and turbinates, and generally, it is not directly related to the body's own immune system. Another difference lies in the symptoms. The main symptoms of chronic rhinitis include nasal congestion and runny nose, with some patients possibly experiencing headaches or dizziness. In contrast, symptoms of allergic rhinitis mainly include itchy nose, sneezing, and clear nasal discharge, with some patients possibly experiencing nasal congestion. In such cases, it is necessary to visit an otolaryngologist, allowing an experienced doctor to make a diagnosis, supplemented by additional diagnostic tests.
