Sorry about your foot problems. Any consideration given to complex regional pain syndrome as a diagnosis ? It seems as though you have been through a lot with those foot injuries. I had the boot, crutches, cane, all kinds of mobility issues. Finally I saw a physiatrist, got proper diagnosis and then my journey to recovery. First step was to get rid of the boot! Ugly thing. Then Physio by a specialist in CRPS. Final step to getting over the last little bit of pain was walking every day. Good luck. Hope this helps.
