Ear pain and block. Than combiflam.

Got cold and suddenly since yesterday my left ear got blocked and pain started. Pain got heavy and by evening i started feeling dizzy. Consulted Gen Physician and he prescribed the medicine listed here. 1 day gone but ear pain keeps coming back in 4-5 hours and I had to take Combiflam every time. Also started with Ciplox ear drop by consulting the doctor. But I feel the ear pain is returning back every 4 hours after the pain killer effect goes. My left ear is still blocked and I can feel lots of cough jammed in my nostril and surrounding areas. No coughing or fever. Dizziness has come down to a lot extent after medication, but only issue now is the returning ear pain which slowly turns bad is not taken combiflam. Please suggest an effective long term relief option which can work better than Combiflam.
