The unrelenting cold on my feet and now in my hands is the most difficult type of pain I have - I've found nothing gives me relief, meds, toe warmers, extra socks, mattress covers w/ built in heating pads, warm epsom salt soaks, etc etc. It's reached a point now where I can turn a heating pad on high but I feel no warmth on my feet yet I still have feeling in my feet so that's a good thing.
Only solution offered was mega doses of mexelitine, a class I antiarrythmic that the chief neuro of a diabetes program told me was successful w/a few of his patients who suffered from cold pain. My cardiologist and I opted out for other reasons.
