Hi, I am a 41 caucasion women who is having some strange symptoms. I had my blood drawn fro workup recently and it showed that my Vitamin B12 was 198 and my chloride was high and calcium low. I have had episodes of burning in my thighs that come and go and feel like they are on fire. I am extremely tired, I get dizzy all the time and someday I have a hard time talking. I forget easily and can't remember basic stuff somedays.
