I posted about this a day ago. I have this and it gets worse every day. To be honest I cant take it much longer. My feet feel like they are dead, spongey yet feels like walking on bone. My feet deformed too and I walk in the sides of my feet. It started with the sponge feeling but I have it in long fibre and motor too. Exercise makes it worse so havent found anything. Im quite scared that I have charcot foot.
