I have been on T3 only for about 18 months under the guidance of Dr P. Following a recent health scare, I had many tests and the blood test came back with a below range T4 (which I understand is because of the T3 although my Doctor doesnt realise this). However my TSH is 7.5 which I realise is high and rather than increase the T3 I wondered if I should add some T4 (again advised by Dr P). I have taken 25mcg of T4 on two consecutive days and ended up feeling agitated and with a headache. I cant remember what taking T4 was like and I dont think I got headaches with it. I definitely dont remember being agitated.
Do we think this is because my body is a bit in shock at receiving T4 (it is only 25mcg after all) and is this normal? Not sure if I should take another dose today.
By the way, I am extremely depressed at the moment and Im assuming this is because I am obviously hypothyroid again.
