Hi, just looking for some opinions.
Recently had my thyroid checked,
TSH 5.8 (0.3-5.5)
FT4 14 (10-22)
2 years ago it was
TSH 8.5 (0.3-5.5)
FT4 12 (10-22)
Also had my antibodies done
Is it normal to have symptoms even when my FT4 is in range as have been feeling extremely tired lately and some brain fog. Just wondering whether it is related?
