Hi Chris,
Welcome to NeuroTalk!
I would absolutely ask for a referral to a neurologist if I had the concerns you write about.
You will likely get much more feedback on dietary supplementation and on potential neuropathy from the PN forum here:

I don't know if you are experiencing repetitive strain injuries due to the increase in yoga? The repetitive strain injuries forum is here:

Please make yourself at home on any of the forums here at NT!
Hope to see you around the forums!
Warmly,
DejaVu
