The problem is not with you, it is your doctor. Doctors have been trained to think that TSH tells them all they need to know to diagnose a patient for thyroid status. Unfortunately this is wrong. There are two basic types of hypothyroidism. One is primary ( Hashimoto't Thyroiditis) and the other is called central hypothyroidism, which is related to malfunction somewhere within the hypothalamus/pituitary area. Central hypothyroidism is characterized by relatively low TSH, even with low Free T4 and/or Free T3.
When doctors go beyond TSH and test Free T4 and Free T3, they will then fall back on "Reference range Endocrinology" and tell you that a test result that falls anywhere within the range is adequate. That is also wrong. The ranges are far too broad, due to the erroneous method by which they are established. Free T4 needs to be at the middle of its range, at minimum, and Free T3 needs to be in the upper part of its range, or as necessary to relieve symptoms.
A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve symptoms. symptom relief should be all important, not just test results, and especially not TSH results. You can get some good insight from this link written by a good thyroid doctor.
So you are going to have to convince your doctor to treat clinically, as described, or find a good thyroid doctor that will do so.
My TSH reads 6.35 mlU/ML, but with normal Free T3 and T4; what does that mean and should there be treatment? My symptoms are excessive, I saw the endo dr for long term chronic pain issues along with all the others that coincide with hypo.
Also, how critical is the conditions of the test? Endo wanted a 12 hour fast with an early a.m. draw. My TSH test a year ago was within normal range, but was in the p.m. and no fast. I had the same exact horrible debilitating symptoms going on, but a normal test. Any thoughts on testing conditions?
I should have posted results?
