No, I am healing the Autonomic Neuropathy (Dysautonomia/POTS) with supplements and diet. It is going very well! I was unable to sit up or walk. Now I can walk and do more.

I have also had CFS for many years and that is doing really great.
To answer your question, my hands used to be cold and my feet also. I wear socks or SOFT UGG slippers at home. Even in summer, but the AC is on keeping me cool. With Dysautonomia, you cannot keep your temperature regulated. My hands and feet are much better now. I can go without slippers and sleep without socks now. I am improving.
I hope you can figure out exactly what is wrong. With Dysautonomia, everything automatic stops working so there are many problems. Adding that to CFS and wow, it is a mess.
