Last week I felt bit pain in my left ear after which I used earwel drop, after this I felt as if my ear is closed due to some vaccum or something and after 2-3 days I started feeling a whistle like sound in my ear. I checked with the dr he said your ears are clean and there is no issue but I could still hear that whistle sound in my left ear. I am not sure what I should do to fix this. Please help
