Your symptoms â intermittent nasal block, ear popping, right-sided headache and eye socket pain, and cold sensitivity â suggest chronic sinusitis with possible Eustachian tube dysfunction. A deviated septum may be contributing. Since Fluticasone and Montelukast-Desloratadine haven't helped, this needs further investigation before deciding on surgery. Septoplasty and FESS (sinus surgery) are considered only after imaging confirms the extent of the problem.
Next Steps
Get an HRCT PNS (CT scan of sinuses) to assess septal deviation and sinus disease. Then consult an ENT surgeon who can review the scan and advise if surgery is warranted. In the meantime, try saline nasal rinses twice daily for relief. Consult me on Practo for further guidance.
