it wasnt for quite a period of time before i had any type of blood tests for toxins. Even though i started to show symptoms of PN about a month later, I had no idea of what was going on, first thinking i had an ingrown toenail, then later that my back was the problem. I do have quite a few herniated and bulging discs. It took two years before i realized that i had PN (after researching online numb painful feet and finding the braintalk website) and a few months after that that a diagnosis was made. I was dealing with numerous respiratory infections during those years over 25 of them the first two years alone and was trying desperately to keep working, i had young children. Because of the period of time elapsed and nothing showing in blood then i could never get a doctor to initiate a chelation though i did do one outside of the main medical establishment. This goes back to the other thread and you and others helped me in ways you will never know.
