Hi there. I am hypothyroid and take desiccated thyroid. Lately I am having really bad heart palpitations, so I went a few days without thyroid, thinking it was possibly to much. I only take 1.5 30mg tabs. It did not change. I also am completely bone exhausted, and am having numb hands again. In the summer I had iron ivs, and the numbness went away. I am seeing a new doctor and having labs done shortly, just waiting for the proper days in my cycle. In the mean time..wondering if anybody has advice? Thank you.
