I'm posting at 3am ,can't sleep yet again due to painfull joints . I was diagnosed 10 years ago with hypothyroidism and initially took 25' then 50 now 75 thyroxine . My recent blood test was TSH 0.4( 0.01-5) t4 22( range up to 20. T3 4.2 ( 2-6) have had blood tests looking for raised esr but seems ok . My whole body is sore , throbbing even my ribs . I'm wondering if the Throxine is causing this it is def worse than it was a few years ago when my TSH was 8 . Would a change to armour be a possibility , would my dr even consider it .?or do you have to buy privately . I'm at a loss as how to best cope with this as I know I will feel so tired tomorrow Thanks for you thoughts .
