Happy New Year everyone. Hoping we will all find the answers we need.
I'm feeling confused after a recent visit to an NHS endo. I had asked for a referral to him, having found him on the Thyroid UK list, which indicated that he had prescribed T3, and found positive info when I researched him online. I would be grateful for any comments and advice on the outcome of this visit. To set the context, I think it will be helpful first to list some test results:
Date Dose Results Lab

Now for the story! The problems began when I had Covid in late September 2023. Until then I was doing well on 100mcg Levothyroxine. After Covid I had PVF and finally consulted my GP practice in February 2024, and was seen by a nurse who ordered blood tests, including TSH, for which I wasn't forewarned, so it was done late in the morning, and I had taken my thyroxine and had breakfast. As result my Levo was reduced to 75mcg, and within 6 weeks I could barely walk. I had a private test (first results, above), and sent them to the GP Practice with a request for a trial on 100mcg and a test including T3 after 6-8 weeks. This was agreed, and within a week all my energy returned and I could cope with life and do my daily 40 - 50 minute walks easily. But when the NHS blood test was done T3 was omitted (second results above), and the nurse wanted to reduce to 75mcg agin. I held out, saying that I had been very unwell on that dose, and after consultation with the doctor, it was agreed that I could stay on 100mcg for a further 2 months. and then retest. I continued to be well, but decided not to be caught out this time, so had a private test just before the upcoming NHS one. (Third results, above) This gave a very high free thyroxine figure, so I reduced my dose to 75 and 100 mcg on alternate days. However, the NHS test (fourth results above) gave a much lower free thyroxine result, though still over range, and I continued alternating the dose, after a battle with the physiotherapist, who had now taken over, and who wanted me to revert to 75mcg.
Unfortunately at the end of August I again had Covid, followed again by PVF. Finally in November I had a telephone appointment with the GP, who suggested a referral to an endo, which was when I asked to see the doctor mentioned above. The appointment came through surprisingly quickly and I saw him on 4th December. However, his attitude was not what I had hoped for. I had listed for him all the tests shown here, but he waved them aside, saying he had seen my NHS results and they were all he needed. He said that I was overtreated, and dismissed my comment that although TSH and T4 indicated this, T3 was on the low side. He told me that T3 is not important; T4 is the active hormone and the correct way to treat hypothyroidism is to get TSH and T4 in range. On the basis of the history of the effects of two Covid infections followed by fatigue symptoms, he said that my problem is due to PVF, and proposed waiting for that to resolve, then doing a telephone appointment after two months with a view to reducing my dose initially to 75mcg and subsequently reducing further. Noting that my weight is 45 kilos, he said that I should not be taking more than 75. This I think is correct, but I wonder whether a combination of T4 and T3 might be helpful, especially as my results seem to suggest poor conversion according to Paul Robinson's formula.
I'm sorry this has been a long post, but I felt you needed the full picture, and I would really appreciate some advice on the way forward. Many thanks in advance.
