You seem to have a Deviated nasal septum
from the symptoms you have mentioned. you should consullt an ENT surgeon and get a DNE (diagnostic nasal endoscopy
) done , which will reveal the condition of your septum, the condition of sinus openings and if there is any mass in nasal cavity
and treatment depends on the diagnosis. If you have a deviated septum you will have to get septoplasty
done, which is a corrective surgery for DNS.
wish you good luck.
