Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain congestion, bad smell from nose and release of green and dry mucous seems to be most commonly due to
Sinus infection or
Sinusitis.
As the sinuses drains through nose therefore infection and fluid accumulation in sinuses lead to congestion, bad smell and discharge from nose..
I would suggest you to consult an Otolaryngologist and get evaluated and a thorough clinical evaluation and investigations like PNS Vie x ray or MRI scan can help in diagnosis and treated accordingly..
You can be advised a long course of antibiotics, anti inflammatory painkiller, decongestants like Pseudoephadrine, mucolytics that loosens the mucous and ease in drainage like
Ambroxol..
You can also do saline nasal irrigations, steam inhalations and use decongestnat nasal sprays containing
Xylometazoline..
Use a humidifier in your room..
In case if still there is no improvement you can be advised Endoscopic
Sinus Surgery..
Hope this information helps..
Thanks and regards.
