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.

I am not an expert, but while you are waiting for an expert to respond (we have many really marvelous people on this forum), consider that B12 is a water soluble vitamin. The body throws off any excess B12 that it doesn't need. Given that this is the case, I don't see how taking B12 can cause too much harm.

Good luck.
