Hi, so I have pretty persistent cold intolerance, along with sleep disturbance, muscle pain and fatigue. So my doc always checks thyroid. I had her print my blood results and my ft4 the past fee years has been 16 -17 and tsh between 0.7 and 1.5.
Now my most recent results are ft4 12.5 and tsh 1.5, she says that's fine. I guess because its within reference ranged, but why has my ft4 dropped like that? And isn't tsh meant to rise when that happens? I'm just wondering should I be concerned?
