Hi Jeanie,

Thanks for asking.

To be honest, that's a good question. I know my Doctor mentioned someone that had been brought to him in a wheel chair. My Doctor was so sad about it as he said that had they brought her sooner, she would be ambulatory again. And it was a B12 deficiency.

What I take away from that is namely this: B12 is a lot more important than we think and it pays to get things investigated early, it pays to be on forums like this one here and share information.

At the end of the day (or post), someone more knowledgeable about B12 deficiencies will probably need to answer that question for a quick answer. It is something I will probably research though, especially given my own need for B12 supplementation.

Personally, I've noticed that my back starts to sort of 'freeze up' if I go more than about 10 days between B12 shots. And my attitude begins to suffer as well.

Hope that helps Jeanie.
