Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain
nasal congestion can be due to a number of causes like common cold,
sinus infection or sinusitis, nasal polyps, allergies, deviated
nasal septum, foreign body in nose, etc..
I would suggest you to consult an ENT Physician and get evaluated and a thorough clinical evaluation and investigations like nasal endoscopy, x ray of
Paranasal sinuses, MRI etc can help in ruling out the exact cause and will be treated accordingly..
As of now you can do steam inhalation, use a decongestant nasal spray like
Xylometazoline and also sleep with head slightly raised as compared to feet..
Hope this information helps..
Thanks and regards.
