Doctor's answer:

It is likely caused by an upper respiratory infection. Currently, active anti-inflammatory treatment is sufficient. It is recommended that you try taking carbocisteine granules combined with cefixime dispersible tablets for treatment. Additionally, make sure to rest and drink plenty of water.
