I know a deficiency of B12 can, but I test all normal (haven't done urine MMA). But I have had chronic muscle pain ever since taking relatively high doses of methylB12 and methylfolate. I wonder if taking either one somehow drained my B12 and caused SFN. I don't have typical neuropathy sensations, but some SFN symptoms and annecdotally, SFN can present with muscle pain.

As Nervous has already stated B12 and Folate ( vitamin B9) are water soluble so they pass through our bodies quickly. B12 is key to nerve healing and regeneration. I take 1.5mg of Methyl Cobalamin daily (1500ug) I think your muscle soreness symptoms have arrived coincidentally and you are erroneously attributing this to B12 consumption. Consider a Magnesium supplement. It is good for both PN and muscle soreness.

Best wishes
