Hi Dew -
About that wheelchair, my neurologist, who graduated from medical school around the time you were born, was of the same opinion: his job was to get people out of wheelchairs, not put them in them.
What turned him around in my case was just a list of all the things I could not do without a wheelchair. And thankfully, there were no WC issues to deal with, having injured both feet at the gym.
So I would suggest taking Hopeforthebest's advice to heart. You might even want to maintain that list of all the things that come up on a daily basis that you just can't do without a wheelchair. (I presume you've been through a regimine of PT/OT, if not you should do so, WC allowing.) And to test the scooter hypothesis, you might want to rent a wheelchair for a couple of days, just see what your upper body strength is like, vis-a-vis the real world.
take care,

Mike
PS This was obviously posted before I read your subsequent thread re WC approval, which is wonderful news.
PPS And this was obviously before I realized that I had confused H4TB's thread with yours!!!
