Yes, Oui, Sí, Ja, Da....I am answering of behalf of millions who are suffering symptoms with normal lab work. :)
"The problem lies in the fact that the exact amount of thyroid hormones entering the cells is impossible to determine with a laboratory test. And there is no exact way to measure what takes place inside the billions of cells, where thyroid hormone controls the rate of metabolism." - Excerpt from the book "Cracking The Metabolic Code - The 9 Keys to Peak Health" By James B. LaValle, Stacy Lundin Yal.
It's very common for symptoms to be present before lab tests show a problem, particularly, if you have Hashimoto's Thyroididis.
Have you been tested for thyroid antibodies? Those would be Thyroid Peroxidase Antibodies (TPOab) and Thyroglobulin Antibodies (TGab). You need them both, because some people have one of the antibody's, others have the other one and some have both. Elevated levels of one or both of these tests will determine if you have Hashimoto's.
You should also get a thyroid ultra sound, if you haven't had one, as that would show swelling/inflammation of the thyroid, which is also indicative of Hashimoto's.
