I have Reynaud's. I have no idea whether PwMS have a higher percentage of incidence.

I have B-12 Deficiency. I think I read somewhere, and I know someone will correct me if I am wrong, that PwMS do have a higher incidence of B-12 deficiency.

I was recently dx'd with CRPS. There are a couple of studies out there that suggest that PwMS have a higher percentage of being dx'd with it than P w/o MS. That was in one of the CoHort studies I read - it was a small study.
