Children with sneezing and yellow nasal discharge can choose sea salt water nasal wash to moisten and clean the nasal cavity for treatment to promote smooth flow, while it is recommended to drink more warm water and keep the room clean and air circulation. If the child’s symptoms are not relieved by the above methods for a week or so, it is recommended to bring the child to the rhinology department for further examination to determine whether there is rhinitis or sinusitis. In case of allergic rhinitis, anti-allergic drugs can be given, and in case of sinusitis, anti-inflammatory treatment should be given.
