I have had Raynauds for the past 7 years and now over the past 12 months, I have had a buzzing sensation( like a electic stem pad) on my left shoulder blade. These past 4 weeks it has spread thru my back and neck and is now going down arms and down my side. I feel it almost continuously. I work for a chiropractor and he seems puzzled. A year ago when this started, he suggested that I take a B12 supplement which I have been taking faithfully. I had blood taken yesterday to make sure I am not defienciant in any vitamins or minerals. Next step will be an MRI. Anyone have advice for me?
