Whoopie! No headache since starting 50mcg thyroid hormone middle of last week (a jump up from 25mcg). I was having daily migraine-like headaches and had 3 visual auras in one month. Is it coincidence or the higher amount of thyroid hormone? Whatever, I feel better than I have have felt in a long, long time. Joint and muscle aches are improved too! I just hope that this continues. Also, doctor told me I have "Autoimmune Syndrome" (3 or more autoimmune diseases at the same time -- one of which needs to be autoimmune thryroiditis -- either Graves or Hashimoto's). Had never heard of such a thing, then found it on the internet. In fact, there's lots of info on it. Basically, they just treat each thing individually, but it ties it all up into a neat little bundle.
