Please ask your doctor to run a basic thyroid panel - TSH, free T4 and T3. If these are abnormal, you should then be tested for thyroid antibodies.
Ask your doctor for a copy of the lab report. It should show your level plus a "reference range." If you post these results on the thyroid board here at HW, the members there can help you understand them.
