Thanks for this information. I recently found out that three of my siblings are carriers of the hemochromatosis gene, and one of them has tested high in ferritin, so is going to a specialist for further testing.

I just went to my primary Doc yesterday, and he agreed to test my ferritin level. He also agreed to test me for celiac disease, since I have a sister with that disorder as well. Still waiting on the results of those tests. (One of those weird times when you're not sure if you want the test results to be positive or negative. I don't want to have a chronic disease, but if it is treatable and turns out to also be the cause of my PN - maybe it wouldn't be so bad.)
