How to deal with a 1-year-old baby constantly having a runny nose for a month

Patient's question:

No

Doctor's answer:

The one-year-old baby has had a runny nose for a month without improvement. On one hand, it may be related to the baby's upper respiratory tract infection; on the other hand, it cannot be ruled out that the baby may be allergic to cold air. It is recommended to treat the baby with infant paracetamol and chrysophanol granules. If it does not improve, allergen testing and treatment can be considered.
