Hi I posted a few days back about having a hemithyroidectomy due to a 4.5cm nodule on my right gland that has come back inconclusive on the biopsy . Anyway popped to gp from a repeat prescription as they thought I maybe going through early menopause . Discussing with her today that the medication has not help still extremely tired my bone and muscles ache etc . She pipes up oh will I oct your vitamin d levels were very low levels should be 30 over and under 90 I think and I am32.6 so told me to take a high dose of vitamin d . I have lost confidence in her other issue this is just the last straw . Would any if you know if vitamin d and thyroid issues are related .
