Hi,
Noted the history about having disturbed sleep due to nasal blockage at night, using
nasal spray but of not much of use,
mouth breathing.
All your history indicates that you need a proper evaluation for the cause of your symptoms.
I would advise you the following in such a situation:
Consult an ENT Surgeon for a proper clinical evaluation, ENT
Endoscopy and further relevant investigations like CT scan of
sinuses and so on.
The management will obviously be as per the cause found
For example if there is deviated
nasal septum then you need a surgical correction.
Nasal Polypi needs medical management for 3 weeks and if not successful then obviously surgery.
If there is hypertrophy of turbinates then there are many modalities.
If the cause is something else then the surgery as per the cause found.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T. Chandrakant, ENT and General Surgeon
