I've been on thyroxine for a few years now, took ages to get it to start with and now, in last 18 months or so, feel I am on the right dose, probably. A lot of other health probs so hard ot tell really, but warmer feet!! Does anyone know if the outside of your eyebrows ever recover their hair growth?! I am really just curious, as not that bothered about my shortened eyebrows. I have read lots on subject and have never seen much mention of that.
