I was diagnosed with graves about a year ago and chose not to have the RAI treatment. I have been taking tapazole and my numbers are good. I have been having cramps in places that i didnt know you could have them in like my ribs my neck and under my arms. My endo checked my vitamin D level and it was 9 so he put me on 50,000 IU of D once a week. Since i have been on the vitamin D (6 weeks) my cramps are worse and now i have muscle and joint pain all the time. It seems like everything on my body hurts and after weeks of pain i am really in a MOOD!! I was wondering if vitamin D causes these symptoms and if there is anything that i can do to make things better, faster.
