was interesting to read your article, i sometimes get my right hand that goes freezing cold, and
i get numbness
in the tips of my figers, and
up my thumb. i have just been diagnosed with peripheral neuropathy, i have the problem in both feet and hands, which they call glove and sock syndrome, may be interesting if you have just the glove syndrome. it does sound to me, although i am not a doctor, it is from the nerves, neuro, or circulatory.
