I have an even more complicated situation. I have small fiber PN, which started with a faulty sense of burning while wearing shoes or other situations with pressure. Now it has advanced to pain and cold feet in anything other than "normal" temperature of around 70 degrees. Even air conditioned air causes this, particularly in a car.
As a result, I have to constantly switch from covering my feet with a blanket, shoes, socks, etc. until they start to burn, then switching to bare feet, then they start to feel extremely cold and painful, then repeat. The "Goldilocks zone" is very narrow.
Anyone else have this experience, and any suggestions for how to deal with it?
