I just got my results and they made me nervous аs I might have some sort of resistance.
I am taking 62 T4 and 18 T3 in the morning in one dose. Got down from 200 T4 +18 T3 due to fear of rT3 building up. I was feeling hypo as well.
On the reduced dose I feel the same - skipped beats all day long, slow heart rate, terrible bone and muscle pain, brain fog, fatigue, horrible constipation, brittle nails.
I am trying to up my T3 but cannot tolerate it, elevates my heart rate a bit.
My results 22 hours after previous dose:
FT4 19.25 (12-24)
FT3 6.85 (3.95 - 7.80) Some labs here give 8.80 as an upper range in the same measurement units.
When I was healthy I had seen the following results:
FT4 24 something
FT3 7.40 +
When I was becoming hypothyroid, I was very ill, symptomatic, having the following results:
After giving birth when I was not taking any thyroid medication, I was euthyroid at FT3 6.60 and FT4 18.75. However that was a natural rise in FT3, not a medically-induced one and only 10 days after the blood was drawn I began experiencing hypo symptoms.
That is why I assumed that my hypothyroidism begins when my FT3 level falls down below 6.60.
Now it is 6.85 and I am still hypo.
Question is : Do I need just a higher level of FT3 to feel fine when on medication? Paul Robinson says that he has seen a level of 8.5 even 9+ on his blood tests and he attributes that to his body having something broken at a cellular level and requiring higher blood levels of FT3 to feel fine.
Does T3 pool in my blood? And I have hormone resistance?
Is it possible that I have a rT3 problem?
P.S. Going by symptoms I expected something like a 5ish FT3.
I feel the same with this FT3 of 6.85 as compared with an FT3 of 4.99 when I was on T4 only. The same!
Does my T3 pool in blood and show a higher but not realistic FT3 level while I still get my cellular FT3 level from FT4 converting? Is that why I feel real bad when stopping T4?
