I am so very sorry that your PN has progressed to the Hot/Cold feeling stage. Your small fibers are indeed confused to say the least. That is what I was told when I tried Horizontal Therapy this Spring. The HT was supposed to help the nerve fibers relearn their correct response. It did help a little but what is really strange is that is seems like my entire peripheral nervous system has been effected. I feel calmer all over.
I can also relate to the night pain. I have to take a sleeping pill (Lunesta) or I cannot rest at all. And the feeling that your muscles and tendons are shortening is absolutely terrible. I think the burning pain is worse but all these symptoms go crazy at night. I think I could work through the daytime pain if only the nights would give me some rest and relief.
Best of luck,
