May sound stupid but....I am wondering if we might eliminate or confirm some possible causes. (Is there anything we all have in common?)

My wife began feeling the buzzing sensation about a week ago.(She is 50) She also began taking thyroid replacement hormones, progesterone, Iodine and some vitamin supplements about 6 weeks ago, My wife and I are Christians, and we recently began praying in tongues, I know it sounds weird, but does anyone else have any similar experiences when their symptoms began? (OK, let me have it!!)
