Hello. I had a TT 09/09. Since then I ve had my synthroid upped to 200, am taking 50,000 of Vit D, 1000 IU magnesium. My Bones hurt & lately I ve begun to have pain in my shoulders & upper arms, but this feels like more muscles. What are the possible causes or am I simply being a baby? There are times when I can t move the pain, weakness & exhaustion are so bad. Thank you for your time. Denyse
