Thank you for your support, and concern, everyone.

I'm not worried about the need for the wheelchair. It's better than falling over. I'll just need to give it a paint job - black with red and yellow flames shooting towards the back, like a rocket ship. Then I'll tweak the electric motor for more speed! :D

I'm actually looking forward to having the surgery, as strange as that may sound, and hoping like mad that it'll give me some release from my daily pain.
