Question
A 3-year-old child has been suffering from a runny nose for a month, with nasal congestion at night. Initially, it was thick mucus, but recently, after three days of intravenous drip treatment for tonsillitis, the symptoms improved temporarily but then returned with clear mucus. How should one handle this situation and do we need to see a doctor?
Answer
A runny nose is common in cases of rhinitis, nasal polyps, or sinusitis. Possible causes include: colds, chronic rhinitis, allergic rhinitis, chronic sinusitis, and nasal polyps. If the child only has a runny nose without other discomforts, it may be due to changes in temperature and usually does not require special treatment. However, if there is unilateral nasal congestion and blood in the mucus, it may be due to a foreign object in the nose.
