Hi..
Welcome to HEALTHCARE MAGIC..
I have gone through your query and can understand your concerns..
As per your complain big clump of smot or mucous struck in nose that does not come out is exactly
nasal congestion and can be due to causes like Upper
Respiratory Tract Infection or
common cold, Sinusitis, Nasal Polyp etc.
I would suggest you to consult an Otolaryngologist and get evaluated and if needed he can also advise you investigations like Nasal endoscopy, PNS view x Ray of sinuses or MRI SCAN to confirm the diagnosis..
In case of Sinusitis you can be advised to take a course of antibiotics, anti inflammatory painkiller, decongestant, steam inhalation, saline
nasal irrigation, and decongestant
nasal spray..
For Common Cold anti allergics and decongestant along with steam inhalation can help..
For nasal polyps Steroid nasal spray, Steroid injection or surgical removal can be advised..
Hope this information helps..
Thanks and regards.
