As far as the B-6, mine was also high--47.4, reference range 5-30. I had small fiber sensory neuropathy in my feet, legs and hands. I also had electric shock sensations in my arms. Two weeks after stopping B-6 supplements, symptoms subsided. The numbness has taken several months to resolve. Unlike your situation, I have an underlying neuropathy that complicates matters, possibly mild CMT. I hope, once you stop the B-6, things will improve.
