Is it possible to go from having Graves and being euthyroid and 4 months off Carbimazole to having Hashimotos? My latest bloods were TSH 1.49(0.20 - 4.50); Free T4 14.3 (7.4 - 17.0). I had some kind of flare up after a busy weekend just before Christmas - I had palpitations, burning hands and body, headache, insomnia, joint pain, muscle aches and tiredness, my heart rate was racing in the middle of the night , I was so anxious I couldn't focus. I went to the GP's had bloods done, saw the Endo who said it was nothing to do with the thyroid as bloods are in range - I asked what antibodies I had as I couldn't remember and he said it doesn't make any difference my bloods are in range therefore it's not my thyroid!! I am really exercise intolerant- my heart races when I do anything too strenuous and I have started to get out of breath! I feel lost I am so anxious I don't know if I have another autoimmune disease as my kidney function seems to be affected when I have the flare ups (I've had 2 now) and coincidentally my GFR result has dropped after each one but thyroid results remain the same and both endo and GP are adamant it's nothing to do with my thyroid!
Does anyone have any ideas as I want to get this sorted with it without the endo and GP before I end up with CKD!!
