Chronic rhinitis is a relatively common ENT disease with various clinical symptoms, the most common of which are nasal congestion, runny nose, and reduced sense of smell. Some patients may experience headaches. In such cases, it is necessary to visit an ENT department. Examinations like a sinus CT and head CT can be conducted to inspect the nasal cavity, sinuses, and to check for any intracranial lesions. If the issue is simply an inflammatory reaction, medication treatment can be chosen. Common treatments include oral medications and nasal sprays, and the nasal cavity can be rinsed with saline solution. During the treatment process, regular follow-up visits are necessary to monitor recovery, and most patients can recover smoothly within about a week. (Please use medication under the guidance of a doctor.)
