I have occasional feelings like an electric shock that run from my fingertips and up my arm towards my heart.  It always happens at night while I am sleeping and I wake screaming and shaking, hitting my arm to make it stop, afraid that I am about to die (if it gets to my heart).  This has been happening for about four years (every few months).Could this be related to B-12 deficiency?  I am a Raw foodist and I have low B-12 and low iron and vitamin D.  I did read something recently that said B-12 deficiency can cause nervous system problems (which this would appear to be), so I ate meat for the first time in many years, but I have stopped as i am not comfortable eating meat, and it seems b12 supplements have more b12 than meat anyway, but now this has happened again and very badly, so I am again uncertain...
Hello, Sharp shooting pain which travel fast and on and off, comes and goes are usually related to multivitamin deficiency. You should go for proper treatment- it D supplement
