Thanks for the info and encouragement!

I did have a blood test last year, I wasn't tested for B12 or mercury but my thyroid was fine, glucose was fine, but my Vitamin D was REALLY LOW:

12.6L Range was 30.1 - 100.0 ng/mL

So it was very low. I started taking Vitamin D pills (5,000 units) one per day. That was about 7 months ago since that test. I will get my blood test results hopefully by mid next week.

I would love to see a Vitamin B12 deficiency or even high mercury levels, as this would tell me my neuropathy is most likely being caused by those factors, instead of something like MS or similar.

I have started taking supplements also.
