My toxin was too much Vitamin B6. I thought I could help my neuropathy in my toes by taking a B Complex which had 100 mg. That is 5, 882% RDA. It made it worse and other symptoms started. The excess B6 accompanied by a dehydrating event caused Small Fiber Polyneuropathy. B6 Toxicity can cause damage to your autonomic, sensory, and motor nerves.
