Thyroid levels, specifically T4

Alexandra
I recently had my Thyroid checked. My TSH level had been a little low in the past, but then normalised. This time TSH is normal, but T4 level is low. 
Questions: have you had this? What did your doctor advise? Mine says we can treat it or not, it's my choice. 
And then-if you are taking thyroid medication, how has this affected you? 
Many thanks for your input!
