I have been underactive for 19 years. my levothyroxine was increased in aug to 175mgs. i still feel yuk so ordered further tests from gp
serum tsh is 0.08 it was 4 in august
serum free t4 is 23.0 they state high.
Does this mean 175 is ok. do i need t3?
I am reluctant to reduce my dose again as i was very poorly and couldnt function.
