It's so weird, this sudden onset, and for it to be so much worse in the same ear that was already so much worse because of acoustic trauma. The doctor was figuring SSNHL, or else some weird cold/virus, but the audiologist mentioned he's seen acoustic traumas worsen over the years, and i told him noise induced hearing loss is usually dips at 5 6 12k etc, he said no he's seen noise induced skiislopes in truckers and stuff. I dunno what to make of that. The one thing is using valsalva maneuvre it is difficult for me to open the eustachian tube of the bad ear, but i think it's always been that way. after the ear cleaning the doctor said it looked find, so he went with prednisone, mri, and ent referall.
