Hello, @gcattnu ~
I, too, have sensitivity to cold, especially in my feet, and to a lesser degree, my hands. My diagnosis was distal symmetric axonal-demyelinating sensorimotor PN, and I am currently receiving the deep-tissue (Class IV) red light therapy from my physical therapist. In fact, I have had these treatments for at least two years.
However, she also introduced me to BEMER therapy about a year ago and I have found that this gives me more of a feeling of over-all wellness (or at least betterness!!) like none of the other therapies that I've tried. The acronym stands for Bio Electro Magnetic Energy Regulation and in a nutshell it reintroduces blood flow into the tiny veins and capillaries that no longer enjoy that source of oxygen and nutrients (because of age?) that the main veins still receive. A better explanation than I can give can be found on the BEMER website. As an aside, I also have a large heating pad under the fitted sheet and I sleep with that on the high (but not highest) setting all year long. I do believe that there are more benefits than warmth to opening all those tiny veins that are meant to function as carriers of oxygen and nutrients, so I'm all on board with this.
It's another idea for you - hope you are able to find relief!

Hi, gcattnu39 (@gcattnu39)

No, feeling cold––or “chilled” might be more accurate (“cold” seems a bit extreme for what I feel)––doesn’t get worse no matter how long I remain in any given set of surroundings. The only way I can lessen that feeling of being chilled––assuming I can’t just get up and leave––is to don a sweater or heavier shirt.

I did do TENS therapy many years ago, but for balance (enlivening sleeping soft tissue), not specifically because of neuropathy (I hadn’t been diagnosed yet) or anything like unusual sensitivity to heat or cold. I didn’t continue with TENS because it wasn’t helping.
