go to a doctor that specializes in thyroids - i've had trouble for years and on meds but recently was sent to a specialist and he ordered labwork for TSH, Free T4 and Free T3 tests. Our local doctor's clinic couldn't do these tests, had to go to hospital and even they didn't do one of them and had to send it to another more specialized lab. The 'free t3 & t4' is not the same as regular T3 & T4.
