went deaf in left ear years ago after mylogram (sp) - neuro said it was quite possibly because there had been an air bubble left in my spine when they removed the dye from my spinal fluid - got hearing back after a month or so but then started tinnitus in that ear which quickly progressed to both ears and now I have tree peepers year round in my head - sometimes really loud - had ears tested and there are some frequencies I can't hear at all - like birds and people with higher pitched voices or who speak softly - have small hearing aids that I can't wear when I wear my glasses because of feedback when they touch - hearing aids over ears not in so have to choose - see or hear - generally I pick vision - and lately anything remotely loud drives me crazy - like my husband watching TV or listening to the radio - ears have gotten quite sensitive I guess - and it would be the MS I think -
