High frequency sound (noise) in the left

I cleared my left ear with earbud 4 days backing, while doing it there was blood on the bud, which i think is due to rashing on path and not on the eardrum. After that next day ear was paining and on day after that pain became unbearable and i consulted an ENT doctor who said that it's due to infection and ear has small pimples like on the inner boundary or pathway. Then pain was relieved by the medicine(Flexon &  lbx) but as the pain killer effect vanishes, unbearable pain occurs. Then i consulted another ENT and he said i rashed surface of ear which caused it. Now one day after that, i started hearing continuous high frequency type noise in that ear when complete silence is there. I didn't touch eardrum while cleaning with earbud.
