I think it might be different for different people, but iron was the thing that finally made the foot pain go away. It only took a few days. I'm taking 29mg of Ferrous Fumarate, but I'll probably switch to Gentle Iron after this. It's easier on the stomach and not as likely to cause constipation. Gentle Iron is not a brand; several companies make it. It's Iron Bis-glycinate AKA Ferrous Bis-glycinate (sometimes the bottle just says iron glycinate, but just look for Gentle Iron.) Also before I took the iron, I took some extra Iodine and it helped a little, but when I added the iron, pain went. The kind of Iodine I've been taking comes in two brands that I know of-iThroid and Iodoral and it seems to me a large amount of Iodine so I open the capsule and take about 1/4 of the cap a day. Taking the whole capsule every day caused acne.
