In August of last year I had my medication increased to 100 mcg as my TSH levels had risen to 6.5. I had spent a number of years on 75 mcg. My TSH levels came down to 2.83. On my last blood test it has risen again to 3.31. I spoke to the GP about this questioning if my medication needed to be increased. She told me she was reluctant to do this, as I was on the borderline and that if she did increase I could go Hyper thyroid and that would be much worse, than the excessive tiredness and pin/needles in my hands. My question to the group, is having read a number of posts, most state that TSH levels should be 1 or below, is my GP correct in stating that my level is ok? Thank you.
