I would have lots more questions to ask of P.M. Dr.:

Even if you didn't have CRPS how would you be better able to walk without that toe? Would you have extensive physical therapy to kind of learn to walk again?

Vrae is probably right that it shouldn't be done at all but I'd ask If amputation was performed
what methods ie: nerve blocks would be used to prevent a flare up back to square one of monster CRPS?
If that happened it would be nearly impossible to walk due to extreme pain
anyway & that's where you are now.
Is there a certain age past where it's unlikely to come out of remission?
I mean say for children, it's more rare to even get CRPS/RSD but they also have
far greater chance of remission (as it should be).
