Hi, I am Dr. Atul Kumar Nimawat MS ENT You may be experiencing a subacute viral or allergic rhinosinusitis with sinus pressure-related headache, possibly accompanied by upper respiratory tract inflammation. Cough-related headache and facial heaviness often indicate sinus congestion or postnasal drip. Since the symptoms are persisting beyond a week, secondary bacterial infection or persistent allergic inflammation may also be contributing factors.

Get physical examination

You need to get examined first and then medication can be prescribed accordingly. Meanwhile to get relief from cold & cough, take steam inhalation and stay hydrated.
