Welcome to healthcareMagic forum,
You might be having borderline hypothyroidsim and so it might have not manifested all the symptoms of hypothyroidism
.Other symptoms of hypothyroidism include weight gain,puffyness of face,hoarseness
of voice,loss of temperature sensation etc.
Firstly you cross check your reports with other standard lab and if that also is positive than you need mangement for hypothyroidism.
Hope this helps,
