Hi, I'm new on here too. I was just reading a few threads and going to introduce myself under new people, when I found what you wrote. I had the same problem, for 10 years. Everything was in my head, fibro, or possible bipolor. Then a year and a half ago, Dr #4 found my thyroid numbers were off. Once on meds for it, it has really helped some of my problems. Now, I'm still having issues with balance, double vision, tight muscles, sudden pains in my head, and a few other great things that I've had for around 5 years. So my new Dr is sending me to a neuro with specialty in MS. She thinks this may be the other part to my puzzle. I see him in Feb. But anyway . . .I wanted to tell you about the thyroid. I wish my Dr would of ran the bloodwork for it 10 years ago.
