For the record

Hashimoto's thyroiditis: in which one's immune system rages against one's thyroid.

This leads to decreased function of the thyroid, which is supposed to be super easy to test for. If one's thyroid hormone levels are normal, then surely one should be just about fine until this decrease in function occurs.

**loud "errrt" noise**

A Hashimoto's patient can have normal thyroid levels, but find herself in quite decrepit condition. That, is not even getting into the debate about what should be considered 'normal' thyroid range. Apparently there is more to consider with Hashimoto's than the typically resulting hypothyroidism (or hyperthyroidism).

Last winter when things took a turn for the worse, I actually thought I was following my grandmother into the land of Lupus and/or Scheroderma. Nope. But my immune system is displaying a sad lack of grace here, what with the attack on my thyroid. Like a basketball player scoring a point for the wrong team. Tisk, tisk.
