Creative new mobility aids

Please ignore the messy background.... This was from a pain spiral day that finally let up, but I honestly forgot about what other room looked like...
True story though... When ER was still on network TV I was actually kinda jealous of the gal with arm crutches because they seemed so much more practical than regular crutches, and more freeing than a wheelchair... And I've been living with that mild jealousy ever since... Until now .. and now I just don't understand how they are more helpful than crutches?.. am I doing something wrong? Or is it just a wrong fit...?... For now I'll keep to my crutches, because at least they don't hurt my wrists
