Welcome to icliniq.com.
Thanks for your query. I understand your concerns.
The nasal block is a common issue, and it is usually due to allergy and increase in the winter season.Also, there is Aspirin-induced nasal block and it should be excluded.
I suggest Physiomer nasal spray before bedtime. You can use Otrivin (Xylometazoline 0.025%) nasal drops from time to time, and it is very effective.
Do you have any allergic conditions? Please revert for more details.
