I found out I have slightly toxic levels of B6--and this is what might be causing the neuropathy! I have been taking a multi-vitamin for over 25 years that has 1200% the amount of B6 necessary, though it is only 25mg. But perhaps changes to the company that manufactures the vitamin and the changes to my diet over the last two years to include many more plant based food choices have kicked my B6 into overdrive. I stopped the supplement and already the neuropathy is diminishing. Thanks for all your support and suggestions!
