Hi Everyone, I was placed on Synthroid when I was 14 and have been on it over 10 years. However, I still seem to have the side-effects of hypothyroidism as well as CFS. Over the years, before I was diagnosed with CFS, I saw tons of endocrinologists who kept saying that my numbers looked fine with just the Synthroid. Does a need for T3 show up on blood tests or is it just something you have to ask about to try for yourself? It has come up during dr.'s appointments in the past but most doctors said, "Oh, you don't need that." Your numbers look fine. Any thoughts or suggestions? My TSH is usually 2.0 Thank you!
