Symptoms of hypothyroidism and the tests needed?
For the past few years I’ve had an extreme problem with fatigue, insomnia, and being very sensitive to cold weather, along with low body temps all the time. Thyroid problems are hereditary in my family, and I’ve BEEN tested (TSH and T-4 which showed as "normal") but I suspect there are tests they didn’t perform. What other blood tests should I get done? What other symptoms should I look out for? My body is beginning to malfunction right and left from these low body temperatures! Help!

You can have normal blood tests and still have hypothyroidism. If you have all the symptoms, find a doctor from the source I provided and they will treat you even if you have normal blood tests and show most of the symptoms.
