The last three weeks, I have awakened throughout the night with tingling, numbnes and burning in the hands. I even noticed it started only with numbness...pins and needles, but has started to burn.....My right forearm appears to run along the ulnar nerve, thereby creating numbness in the 4th and 5th digit...right hand. it is not carpal tunnel, in that it has occurred in the right door a few times. it is not due to sleeping position. I have tested sleep positions...best on my back, but it is still occurring. I am assuming it is Vitamin D deficiency...it is winter and that has happened in the past. j have also added B 12 and a good general broad based vitamin. What do you think?????
