Slightly low on Ferratin & B12

chickklit

I wrote this on a couple other boards. I am trying to get as many people's advice and information. 

I went to my regular dr on Wed to discuss why my hands hurt in the morning and go numb and tingly at night and sometimes during the day. She ran some bloodwork and the office just called to let me know that my ferratin and b12 are a little lower than what they'd like. I"m not worried....they want me to take a b12 supplement and come in next week for another draw. 

 Anyone else have this told to them or gone through it? What does the b12 do and how does it relate to the swollen, numbness...? I am not overweight, I'm 5.5" and I've gained 17 lbs so far, started at around 125. I think the family around me is more nervous than I am....?

A lack of B12 and ferritin can cause pernicious anemia. The nerve cells of the feet and hands can be damaged, leading to numbness and pain. It can progress to memory loss, confusion, and further central nervous system problems if left untreated.
