... that show definite Hashimoto's (a previous blood test from May showed that I was hyperthyroid). I've never been diagnosed with Hashimoto's until now. I've been experiencing episodes of intense anxiety, hand tremors, lump in throat, depression, mood swings, insomnia, etc... I was reading that these can all be due to the Hashimoto's; however, I consulted with my cousin who is an endocrinologist and he told me that because my TSH is normal now (at the time of my blood test two weeks ago), these symptoms are not likely related to my thyroid. Now I'm wondering if I have a psychiatric condition like Bipolar. Can Hashimoto's produce these symptoms?
