Sounds like you are inadequately medicated. Have you been tested beyond TSH? You really should make sure they always test you for the biologically active thyroid hormones, Free T4 and Free T3, which are not the same as Total T4 and Total T3. If you have any test results on these, please post them along with reference ranges shown on the lab report. You are also likely to be low in Vitamin D, B12 and ferritin. So you need to get those tested and then supplement as needed to optimize. D should be at least 50 ng/mL, B12 in the upper part of its range, and ferritin should be at least 100.
A good thyroid doctor will treat a hypothyroid patient clinically, by testing and adjusting Free T4 and Free T3 levels as needed to relieve symptoms. Thyroid med dosage should not be adjusted based on TSH levels.
What is your age??
I have TSH. Aboe 550. I have severe fatigue and loss of motivation and interest in almost all the activities that I previously used to do. I also have pain in the joints. I started thyroxine 300 mcg two weeks ago. I am 33 years old.
Extremely high TSH results are most frequently indicative of an autoimmune disorder called Hashimoto's Thyroiditis. To confirm if you have Hashi's, you need to get tested for Thyroid Peroxidase antibodies (TPO ab) and Thyroglobulin antibodies (TG ab). In addition you need to test for the biologically active thyroid hormones, Free T4 and Free T3, which are not the same as Total T4 and Total T3, so be sure to ask for the Frees. If possible it would also be a good idea to tet for Vitamin D, B12 and ferritin. When you have additional test results please post them here along with reference ranges shown on the lab report and we will be happy to help interpret and advise further.
