Hi.
Nose could be blocked due to several reasons. It could be either functional, like allergic rhinitis, or structural like a deviated nasal septum, polyps etc. The treatment will depend upon detailed history and examination. I would suggest that you consult an ENT specialist In-person/ Online for further evaluation and treatment.
