Go to a different doctor.. Ask around for one that checks for T3.. That is key!! Doctors poorly misdiagnose bc they only check for tsh and t4, not t3. They just assume your t4 will pool into t3 and some people have a problem with that conversion. You have typical thyroid symptoms as well. Some doctors may treat you for symptoms as well and see if you respond on low dose.. look up website called stop the thyroid madness.. and then look into mercury or lead toxicity which causes much trouble for the thyroid. Do you eat a lot of tuna or had you? Do you have amalgrams or did your mother when she had you? Have you had a lot of vaccines? A dmps challenge test is a good way to start.
