A six-month-old baby always has a stuffy nose after a cold goes away, and it always takes two to clear up.

Patient's question:

Duration of illness: Two or three months
Main symptoms: Nasal congestion
Hospital visited: The family always treats it as a cold

Doctor's answer:

Your condition may be chronic rhinitis. Chronic rhinitis is a chronic inflammation of the nasal mucosa and the underlying layer. Its main characteristics include inflammation lasting for more than three months or recurring episodes that do not heal, with intervals of no recovery, and without a clear pathogenic microorganism. It is accompanied by varying degrees of nasal congestion, increased secretions, swelling or thickening of the nasal mucosa, and other symptoms. In traditional Chinese medicine, it is called biyuan and can be treated with Cang'erzi San.
