Hi I had a full thyroidectomy almost 16 years ago. I have to take regular vitamins including b12 injections. Over the past year or so I get deep aches and pains from my shoulder down to my feet my left side being more so pins and needles I can't lean on my left elbow as my little finger and part of my arm goes totally numb. Sometimes it gets so bad I cannot function. My legs are also a problem I get funny feelings in them and feel the need to constantly be moving them. Any advice would be great I don't know where to start at the doctors I also had to request a b12 test 4 years ago after much reading as I thought I had ms my results was very low.
