hi
have been diganosed underactive thyroid for about 8 yrs, was on 125mcg up untill about 6mths ago then lowered to 100mcg but am noe having loads of symtoms, really tired, aching limbs, hair falling out, anexity my lastest results are
tsh 5.01 (0.38-4.70)
free t4 15 (12.0-32.0)
also tested my b12 and that was at 729 (223-650)
but gp has said all normal no action needed but on lab report it says abnormal, should i increase my thyroxine to 125mcg
