Okay - on T3 only and been doing well since 2012. BUT.. for the past 6 months tsh has been consistently high at 6.83 , ( range 0.27 - 4.2) FT3 is 3.8 ( range 3.1-6.8). Have a new GP who has increased the T3, bless her, but still seeing no benefit. (25mcg up to 35mcg and she is happy for me to keep going 40/50mcg until we get the tsh down.
My problem is the more I take the WORSE I feel...muscle pain/dizziness/insomnia etc.
Now something interesting has happened...the past 2 days I have taken NO meds and I feel the best I have in ages!!!!
My question is really about the tsh - how much variation happens in the short term?
I have Hashis and know that I can go up and down, but how quickly can the tsh really show what is happening?
For example have I had 3 test results that show high tsh on THAT day and then swung back to being within range as soon as I take my next dose???? Can T3 really work that quick? Previous test results have always shown a tsh under 1 and my GP has been happy.
Obviously I usually go by symptoms rather than the dreaded tsh anyway but I really don't understand what is happening at the minute. Any comments welcome.
