Hi doctor,

For as long as I can remember I have had a deviated septum which resulted in me not being able to breathe through my nose at all. I got a septorhinoplasty done three years back and a month after the surgery I was able to breathe through my nose and smell.

It has been three years and a couple of months ago, I started to experience difficulty in breathing through my nose. At first I thought it could be a common cold or a result of pollen due to the warm whether. However, 4 months later, I still cannot breath through my nose, I have almost completely lost my sense of smell and I am not able to taste food properly. This has caused lack of sleep, stress and annoyance during the day. What can I do?



Welcome to

You did not mention use of any medication. I am assuming that you are not using any medication now. It appears you have nasal allergy which can create nasal block and other associated symptoms. For COVID-19 also one of the symptoms is loss of smell and taste.

The Probable causes:

Nasal allergy, COVID-19

Investigations to be done:

COVID-19 test to rule it out.

Differential diagnosis:

Nasal allergy, COVID-19

Probable diagnosis:

Nasal allergy

Treatment plan:

L-cetirizine 5mg 10 tablets, 0-0-1 for 10 days.
Saline nasal drops--two drops in each nostril 4 times daily for 10 days.
Avoid cool drinks, ice-creams.

Preventive measures:

Avoid cool drinks, ice creams.

Regarding follow up:

Review after 3 days.
