Yesterday, I was listening to music for around 40mins while travelling in my car. After I removed off the earphones, I noticed a ting sound in my left ear. My fear is that, its almost been 18 hrs and the ting sound is still there... PLS HELP! (has happened before, but disappeared after yawning or other methods by putting pressure on the ear - closing the nostrils) but now Its still there so I m scared...
