I'm so sorry about your hearing loss. I've experienced some, but mine is slowly progressive and in the lower ranges. I have trouble understanding people with low/monotone voices.
I don't "spin" as much as I used to, but I do have trouble with balance. I also have a lot of trouble with visual stimiuli (flashing lights, striped wallpaper, etc) and anything that disrupts balance, like uneven floors. My inner ear is damaged and the balance signals it sends don't jive with the signals my eyes send to my brain, so I feel off balance a lot.
I've learned to compensate for some of it (like a skater learns how to "spot" when spinning), but it can be pretty hard sometimes.
I'm hopeful that my hearing loss won't progress, but if it does, like you I'm also hopeful that there will eventually be something that can be done. Adult (non-embryonic) stem cell research is a marvelous thing!
