Hello, welcome to our site..

By any chance did you get any second opinions on the original foot injury , post surgery? Just to make sure there is no fixable damage that can be repaired?
Preferably someone independent from the original surgeon...
And the most highly rated/ skilled you can find...

But there are some risks of spreading of the CRPS if more surgery is done.. but if the other dr sees something that might be causing some of the pain....it might be worth it.
there are blocks and prevention protocols if a surgery is needed.
