I would like some advice please. Last year I went to the doctors as I was completely exhausted and my joints were aching and I was finding it difficult to go up the stairs at the end of the day. The nurse practitioner suggested testing ferritin which was 28 so in range 13-150. I asked if she could test my thyroid and when she looked at previous results of tsh which I had been told were fine she mentioned they had been at 7 and 6 so might be worth testing. I saw the doctor in August with the results which were tsh 7.6 range 0.4 - 4, which she said was borderline but was put on 50mg levothyroxine as ferritin had also gone down to 18, but was still in range. I wasn't really keen to take it. There is a family history of hypothyroidism. I was given iron tablets to take for a short while. The doctor requested blood tests next to be done in November and to include antibodies but as the tsh had gone down to 2.5, the lab wouldn't do it. They didn't test ferritin again as it had been in range in the August. Then my periods stopped in Oct/Nov. I saw the doctor in February who said it wasn't connected however I had read that it was a side effect of levothyroxine and she agreed I could stop the levothyroxine which I did and my periods have returned. I had a blood test at the beginning of April and the tsh has gone up to 12.6 so have an appointment to see the doctor next week. I don't have any print outs of the results. The lab were asked to test vitamin d and antibodies but refused again to do either. How do you get them to test for this as they are refusing when tsh is in range but also when it is high? I asked if I could see an endocrinologist but was told there was no need. I don't want to take levothyroxine if it stops my periods but I am exhausted without it and my joints ache but should I be taking a smaller dose? Also the tsh seems to have shot up and have I damaged my thyroid by taking the levothyroxine so that now it is functioning even worse than before. Thank you for any advice as I am seeing the doctor on wed.
