Completely what Vrae said

I have CRPS in both feet, worst in my left. The only thing you can do is to keep touching it as often as you can... Don't force yourself to wear socks for long periods yet - work up to it, so try wearing very soft thin socks for five minutes, then work up to ten, then twenty, then move to a warmer sock.... The worst thing for me is tight socks, of they're soft and looser I can bear them much easier.

Different textures are good, start with a soft cloth and work towards rougher textures. Don't let that foot get away with it Just walking around barefoot is really good too, on different textures - just steer clear of really cold surfaces like stone floors, as I find that makes my feet react and burn. Different rugs and carpets are good, as they gently rub your foot as you walk.

I know it's hard, but it's really worth it. I stil get burning, but it's mainly in the evenings now, and by and large I can wear most things except heels...

Good luck

Bram.
