This has all been interesting to me. I have some achiness in my ankles and arms. I have what my doc described as a mild case of hypothyroidism. He wanted to put me on Armour Thyroid, but it caused bloating. We tried Thyrolar, which worked well, but then there was some problem getting it. Now, I take Synthroid. He referred me to this website:

There is the possibility that I might take additional Iodine.
BTW, prior to taking the Synthroid, I had gained weight and had trouble with my hair falling out.
I switched to a mild shampoo (no detergents) and got on more and better vitamins. Also, exercised and ate healthier foods. This, combined with the Synthroid...seem to do the trick in terms of my hair and overall good health.
However, the entire thing has left me wondering about the Thyroid and its need to be monitored. IT seems if it is off, even just a little, it can cause a lot of problems.
