Wow, that's cool. your husband made that for you?

A wheelchair isn't great if you have a lot of cracks etc. You are much less likely to tip over then in a walker, but it is not comfortable and can lead to damage to your skeleton, because you don't have shock absorbers. (mostly if you have some osteoporosis, like I do).

There are many different wheelchairs. I chose mine to be nice looking, light weight, and easy to fit into the smallest cars. it looks quite similar to this http://www.kueschall.ch/en/ULTRAL_897.aspxonly its bright red, with matching wheels. And mine also has a head rest attached to it, because many times I can't hold my head for long on my own.

I have to admit that I do not do much outdoor traveling since I became ill.
We only go walking in places that are meant for that.
we recently got rid of most of our camping equipment because we realized we are probably not going to use it again. (fortunately we can afford to go to good hotels that are fully equipped for what I need).

But, for you there is still a good chance that you will go into remission, with the treatment you are receiving. So, hopefully, it is temporary.
