I too had the sensations in the hands and feet, mostly feet, when I first started on Iodoral too. After I had been on for a couple months and was doing great I started getting an electrical shock feeling along the outsides of my feet. A few times it was very painful when I would get the shocking sensation. I also had numbness in my toes for a few weeks as well. It scared me enough to think about quitting, but I never did. It all went away within a couple of months. Have not had any problems since. I also switched to SSKI /magnascent combo around that time, so maybe that helped or was the cause of it going away? Not positive on that one, could have just gone away if I had stayed on the Iodoral as well. I had completely forgotten about the sensations in my feet until reading your post.
