I saw my wife's aunt who has had MS for a very long time yesterday. For probably the last 15 years she has seemed exactly the same. She uses a walker, but has always gotten around with it fairly well all things considered. You can tell she absolutely needs it, but she could always do a whole lot more than people ever thought she could. I haven't seen her since X-mas and it looks like she is going to a chair full time soon. She was barely getting around with that walker. Granted she is 66 now, but her slip is definitely her MS. Her legs look so stiff now that I was really taken aback watching her try to get around the lodge where we were having the family reunion. We talked at length (she is in the MBP trial and doesn't feel a thing) and she is like "you go for that no matter what it takes, I sure would have like that opportunity". Since I think the gov't is full of doody about 99% of the time anyway, why should I give a crap about whether or not it's FDA approved? I guess I just answered myself on that one.
You have also just described me, although I am a little younger than your aunt. I totally agree with her advice.
