It would be great if you could post the actual results with the reference ranges. But in general, FT4 should be approx 1.4, FT3 should be at the top 1/3 of the range and TSH should be between 1-2. Your numbers may be using different units and may vary however from what we typically see here in the US. Based on what you've posted and your reported symptoms, I'm not sure why you wouldn't want to trial thyroid hormones. Perhaps they might relieve some of the symptoms you are attributing to CFS/ME. Hopefully your Lyme/CFS doctor will understand the importance of co-treating endocrine abnormalities along with the infections. The book, Insights into Lyme, features perspectives from many top Lyme doctors and every single one of them mentions how important it is to treat the endocrine system along with Lyme because Lyme can specifically attack the endocrine system and cause derangements. These derangements may not look like "typical" autoimmune endocrine problems so ignorant doctors may be unwilling to treat them but that is just a good reason to find a new doctor if at all possible. I've never heard of anyone having their thyroid gland permanently atrophy from a trial of thyroid hormone but as I posted before there is a lot unknown at this point. I just think thyroid hormone is so vital to living that I choose to replace it.
