I've been (unknowingly) having symptoms of low B-12 for over two years now. I've experienced rapid involuntary eye movements, neuropathy in my hands and feet, fasciculations all over my body, headaches, joint pain, memory loss, and facial twitching. I had a CBC in January but it was normal, so can one have low B-12 without anemia or should I be looking into other ailments?

And welcome to the forum,you mention you have had a complete blood count,could you post your results on the forum so others can support you in identifying your symptoms and condition.
Here are my CBC results. I never bothered to look at them until now since the doctor told me everything was normal. I am low in Red blood cells, hemoglobin, and Hematocrit. Are those levels low enough to be anemic?
Difficult to really read the tests without the normal ranges (which would be in brackets normally) but the main ones I'd be looking at in relation to B12 deviciency are
MCV (high in macrocytic anaemia and low in iron based anaemia and think yours is towards the bottom)
Red blood cell distrubituion width - which seems towards the high end but think is probably still in range (just)
Don't have problems with iron so not really that up on reading the iron and certainly don't remember rangest that well but think you haemaglobin looks a bit on the low side but still in range.
so, really looks petty inconclusive. Suggest that you discuss further with GP - ask about serum B12, folate and ferritin (which is another marker for iron problems) and please discuss iron supplementation with your GP - or pharmacist if you can't get sense out of GP - before supplemetning for yourself.
According to Medline plus, "This test measures the amount of methylmalonic acid (MMA) in your blood or urine. MMA is a substance made in small amounts during metabolism. Metabolism is the process of how your body changes food into energy. Vitamin B12 plays an important role in metabolism. If your body doesn't have enough vitamin B12, it will make extra amounts of MMA. High MMA levels can be a sign of a vitamin B12 deficiency. Vitamin B12 deficiency can lead to serious health problems including anemia, a condition in which your blood has a lower than normal amount of red blood cells.
Other names: MMA" A CBC does not necessarily rule out a B12 deficiency. One can have neurological symptoms from a B12 deficiency without anemia. Low normal levels of B12 do not necessarily protect from neurological symptoms. Deficiency in vitamin D may also contribute to neuropathy and other conditions as well. So B12, MMA, vitamin D, perhaps thyroid profile should all be checked.
