3. Sensations of Pins and Needles
Nerve damage is among the long-term side effects of B12 deficiency, which explains why people with this condition would feel sensations of pins and needles. Vitamin B12 contributes to the metabolic pathway that produces myelin, a fatty substance surrounding your nerves as protection.
If you do not have enough B12, myelin will be produced differently and this is why your nervous system will not be able to function the way it is supposed to. What is even more interesting is that neurological symptoms that are associated with the deficiency of B12 would often take place alongside anemia. However, in one study, there are about 28% of patients who have neurological symptoms of Vitamin B12 deficiency but did not show any signs of anemia.
Remember that the sensations of pins and needles can happen due to many reasons. But this is a common symptom of not having enough Vitamin B12.
