Did you get tested for Mercury? If you have silver teeth fillings or eat a lot of cheap fish products, you could have mercury levels that can cause forms of neuropathy.

I am getting my mercury and heavy metal urine test tomorrow. I have a lot of old (1980s) silver fillings in my mouth. I am hoping that my tests show high mercury and/or low B12 (from blood test). At least that way I hope to know why I am having the same symptoms of neuropathy like you are having. The nerve zaps, tingling, and muscle twitches & spasms.

In 40+ years, I have NEVER been tested by my dozen of docs for VitB12. How ridiculous is that in today's modern medicine? I had to specifically REQUEST the B12 test and I am getting it for the first time. I had to self-educate myself via the internet. It's really sad that doctors do not test for B12 on a regular basis.
