Have you heard of complex regional pain syndrome - CRPS? I have CRPS in both feet as well as SFN. Just a thought. See pain management frequently. Just had RFAs done in top of both feet. Looking for relief as well as looking forward to nerve to soles being injected. Spine is fairly well destroyed with arthritis and DDD. Don't think Dorsal Ganglion root can be done. Perhaps using my stimulator may be a way but am not sure I want any more surgery that CRPS can invade!
