Breathing difficulty + cold cough.

Hi team I get prone to cold cough frequently not sure of the reason throughout the year. Happening from last 2-3 years consistenly. Got a CT SCAN PARANASAL SINUSES (AXIAL + CORONAL + SAGITTAL) done last evening. FINDINGS: "S" shaped deviated nasal septum with convexity towards the left side and nasal spur on the right side mildly impinging on the right inferior turbinate. Nasal turbinate hypertrophy is seen (R>L) causing partial nasal blockage. Polypoidal mucosal hypertrophy is seen in bilateral ethmoidal air cells with partial occlusion of bilateral maxillary ostia, frontal and sphenoidal recess with polypoidal mucosal hypertrophy and polyposis in frontal and bilateral maxillary sinus (L>R). Mild mucosal hypertrophy is also seen in sphenoidal sinus. Just wanted to know...is this something serious - can it be treated via medicine or does it need surgery.if surgery is it complex. Medication started: Montek LC ( dinner), solspre(3 times ), nezaflo ( 2 times ). Pls suggest
