Hi, Did the specialist administer an Auditory Brainstem Response test...what they call an ABR where electrodes are attached to your head.? That is the only way I know of to diagnose auditory nerve damage. Vertigo and dizziness are some of the symptoms of auditory nerve damage. I don’t think there is any surgery to fix that nerve. Can’t imagine what ear exercises would help that.
As julio4 said, you probably do have sensioneural loss which is benefited by hearing aids.
Keep us posted.

Also, in regards to that podcast...if you log on to the forum and see the page that lists all the groups...further on down you’ll see a Newsfeed area ...I was able to view it there and also in the search area (magnifying glass Icon) on top of page.
