Blocked ear and throat pain. What to do.

On the 14th of March I developed severe throat pain in both my tonsils which turned into visible white spots. As a result my doc recommended Azithromycin for 5 days which I completed. The pain reduced greatly but continued mildly on one side. Cut to the 20th of March, I felt that my left ear was blocked. It hurt at night so I took a painkiller and slept it off. The next day it pained again. As of today, here are my symptoms: - My left tonsil still hurts - Don't really have a runny nose (just occasional water) - No sneezing - no ear pain - My left ear seems to be blocked. I can't hear properly from it. The sound seems dampened. Moreover, when I try and close my nose and blow to pop my ear, I can hear a bubbling sound on the left side, as if the war drum is being pushed by air slowly. Please help on what to do.
