Frostbite

Hi everyone was just wandering I am just about coming out of my worst relaps, I have new damage at c7 which seems to have left me with permanent freezing feet, which burn at the same time(wearied) walking is like walking on hot coals or broken glass. I’m on pregabalin which keeps being increased but doesn’t seem to make much difference. I don’t know anyone who has these symptoms. 😩
