Children's rhinitis is a relatively common ENT disease with various clinical symptoms. Common symptoms include nasal congestion, runny nose, loss of smell, headache, and dizziness. Some patients may also experience snoring and mouth breathing during sleep. For treatment, it is necessary to visit an ENT department to assess the extent of inflammation and type of rhinitis in the nasal cavity. Generally, treatment mainly consists of oral medications and nasal sprays, along with saline nasal irrigation, with a typical treatment period of about one to two weeks. After medication, regular follow-ups are needed to observe the recovery. (Medication should be used under the guidance of a professional doctor.)
