Hello. Thank you for posting your query at DoctorSpring.com
You are suffering from nasal discharge since 4-5 months.Your nasal discharge is mucoid with
black spots and you are not smoker.
It can be due to smoke due to pollution or dust.most likely it may be simple crust(due to
dried secretion). Some time it may be due to fungus infection or nose or sinuses. we need to
get correct diagnosis.
To get correct diagnosis you require by local ENT specialist.
You can do CT Scan of para nasal sinus which will rule out sinusitis and will give detailed
information about nasal cavity and sinuses.
Hope this helps. Feel free to ask if you have any further queries.
Thank you.
Regards
