Chronic rhinitis is a relatively common otolaryngological disease. An acute exacerbation of chronic rhinitis may lead to related clinical symptoms, which often include nasal congestion, runny nose, headache, dizziness, and reduced sense of smell. Some patients may experience nasal discharge flowing backward. After the onset of symptoms, it is advisable to visit an otolaryngology department. Routine blood tests and nasal endoscopy can be performed to help initially assess the severity of the condition. Generally, nasal spray medications can be chosen for treatment, and some patients may also need to combine this with oral medications. Additionally, rinsing the nasal cavity with saline solution can also serve as a supportive treatment. The treatment period generally lasts about one to two weeks, and regular follow-up visits are needed to monitor the treatment effect.
