That is great info. I am going to the Cleveland Clinic in two weeks to have them look at my SFN. I will convey this info. I also have high inflammation, extremely low vitamin D levels, but my B6 was high. I read that B6 may be high because the body doesn't absorb the B6 due to a gene deformity. Also, what is chelation therapy? Thanks for posting this - it gives me hope.
