Use a mucolytic
and nasal drops
Thanks for the query.
post nasal infection
is common. It is usually due to edema of nasal mucosa and hypertrophy of inferior turbinates.
You have maxillary and frontal sinusitis
and this adds to the increased hypertrophy of turbinates. The sinus drainage gets blocked in acute infections more and contributes to congestion.
Please use a mucolytic and nasal decongestant drops for few days and things should improve.
In case the problem persists, do consult an ENT for further evaluation.
Feel free to ask another query.
