Yesterday I heard a strong beep sound when I was on the way. I thought its a horn but after sometime I realized that their was nothing. I heard this sound only by my left ear. I tried it to listen through my right ear by keeping hand on left but. I had listen anything. So definitely their was something wrong with my left ear. When I reached it was ok approximately after 1 hour. But their was headache left side only. I feel heaviness on left side, may be because of headache. Then I take painkiller (diclowin) and I slept. Today its fine but I was worried because same thing happens to my mom before 3 years. Doctor said, that was imbalance of fluid so now she can't listen properly from that side. I am also doing e-learning from 7 days, so whole day I use earphones but this happens to only left ear. Please suggest me something. Waiting for your reply. Thanks.
