It is hard to say without testing.
Bcomplex could be increasing healing in previously damaged areas, and tingling is a sign of nerves waking up (or dying).
The fact that B6 causes neuropathy at BOTH ends of its spectrum --too low and too high--- makes diagnosis difficult when symptoms appear.
Thyroid can cause weird sensations, and so can perturbations in calcium/magnesium status.
There are definitely blood tests for D,K, B12, B6, thiamine, folate.
There are also tests for red blood cell content of vitamins instead of serum which most doctors order. Spectracell labs do these.
