Hi everyone. I have been on thyroxine since last November, after a 2-3 year struggle to get diagnosed. I was started on 25mcg and then, after a blood test in March, my dose was increased to 50mcg. I certainly feel better than I did but, to be honest, I still don't feel 'well'. I have just had another blood testand my TSH level is 0.7 (0.2 - 4.5) which I know is good. My T4 is 14.1 (9.0 - 24.0) and has risen from about 12 in November. I know TSH seems to be the all-important figure but does the T4 level bear any relevance? I don't know whether these results could be the reason for me feeling unwell. I don't like to keep moaning because, like I said, I certainly feel much better than I did. I'd be grateful for any comments.
