Hello, I'm new to this. Have had two year history of hypothyroid symptoms which my GP put down to low iron levels (ferritin of 6) after insisting, he checked thyroid function and I have Thyroid peroxidase antibodies of 1600 but low TSH ( he hasn't done T3 or T4) I am so ill with muscle pain, reynauds type symptoms, fatigue and IBS that I am losing all my self employment contracts. He has sent me away to have my bloods redone in 6 months. I feel really desperate. Can someone explain to me what TSH being non linear means? can anyone point me towards reliable studies I can take to him? All advice welcome. Marie
