My severe b-12 deficiency was discovered last year - though after I began experiencing cognitive, sensory and balance issues. At my lowest (that's known); b-12 fell to 177. Over a year of therapy with b-12 shots, I've now well over 1200. However, recently my b-12 doctor felt it was necessary to check vitamin D levels - and it was low too; 17 as compared to 35 as normal. Is there a corelation? We get vitamin b-12 from food we eat (I apparently no longer absorb the b-12 naturally); and vitamin D from the sun - so what gives? I'm 47 years old with no history of vitamin deficiency issues (though both maternal grandmother and mother both had b-12 issues at some point in their lives when younger)...

BTW, I've been on b-12 shot therapry for over a year now and still have peripheral neuropathy, which is miserable some days (taking Neurotin for pain); does this ever heal?
