Had total hearing loss in left ear some years ago - went to ear MD and he said I was stone deaf and that I'd never hear again - hearing came back along with tinnitus and there are many soft sounds and tones I can't hear - hearing aids are a problem with my glasses as I get constant feedback - being in groups of people is horrible as then I can't understand anything - neuro said deafness was probably caused by mylogram - that an air bubble had lodged in my ear - don't know - just was glad what came back - did !!
