Post Comment. floridagirl11. he electrical current / internal tremors you are experiencing is because of a drop in your hormone levels. It is not directly caused by your thyroid hormone levels, but abnormal thyroid hormones can cause a drop in your other hormones, when then leads to the internal tremor.
