GET THE RIGHT TEST DONE!
If you do see your physician and they agree to do a blood work up, make sure to get the RIGHT test done...
You want:
1) TSH
2) Free T3
3) Free T4
You can have a normal TSH BUT a low T3 and/or low T4.
I feel like an idiot myself being an ICU nurse and I screwed up on this... when I went to the Doctor for my now diagnosed sleep apnea they included a bunch of blood tests for other possible problems, one of them being thyroid. She ordered JUST a TSH, not a free T4 AND free T3 as well... I didn't clarify what she said, so when I got my blood work back I was rather upset (the CPAP has SIGNIFICANTLY helped my lethergy, but there is still some residual, so I'd like to be able r/o my thyroid). So now, I will have to go back to her office, explain this and then get the test done.
