i had a infection in my right ear and lost all but 8% of my hearing in that ear. sometimes my rings like hell. hearing aids make it 10 times better during the day.
at night its wide open most of the time. the only thing that i have found that helps mine is eating less salt. i can eat a salty meal and mine is ringing 5 minutes later. i have found lots of people can eat less salt and not have any ringing at all.
