Forget in-range, the ranges are stupid.
TSH should be closer to 1.0
T3, T4, fT3, fT4 should be near mid-range.
T4 is low re mid-range
T3 is high re mid-range, which suggests possible elevated rT3 blocking fT3
rT3 can be elevated by stress, see the Thyroid Basics sticky.
Training when T and or thyroid function are low is a major stress.
Get fT3, fT4 and rT3 tested as well as a thyroid auto-immune panel.
Has doc palpated your thyroid for size, lumps/nodules or asymmetry?
Thyroid sore? Difficulty swallowing?
It is better to test fT3 and fT4, skip T3, T4
Free Thyroxine Index is obsolete
fT3 is the active hormone, T4 is a reservoir for T4–>T3 conversion.
Is your condition caused by or made worse from iodine deficiency?

Evaluate your overall thyroid function by checking oral body temperatures as per the thyroid basics sticky. Thyroid hormone fT3 is what gets the job done and it regulates mitochondrial activity, the source of ATP which is the universal currency of cellular energy. This is part of the body’s temperature control loop. This can get messed up if you are iodine deficient. In many countries, you need to be using iodized salt. Other countries add iodine to dairy or bread.
