Hi there!

Welcome to the forum! That suggestion about the spare shoes isn't as daft as it might appear - not at all impossible that someone may want to swap the lefts and rights...why ever not??!!

I'm not usually an advocate of major PT beyond what's essential (sometimes it is necessary, of course), but it does sound to me as if your girlfriend could benefit from some gentle long-term PT exercises to do at home, after an initial assessment and course of treatment. It almost sounds like her body has forgotten how to walk, and even if that's really not possible, the therapists may well be able to help with better ways of handling crutches and sticks, and show her ways to put less stress on the body in general.

No, there's no magic wand in any of this, more's the pity. If only....

My RSD is in my left hand/arm, but we have very many forum members with foot/leg RSD, and I'm sure they'll be able to advise you better than I can.

You've come to the right place, anyway....lots of people here with waaaay too much experience of this condition .

Hope we can be of some help,
All the best
