2Tingling Limbs
Vitamin B12 deficiency might cause tingling sensations in your feet and hands. This symptom happens because this substance plays a key role in your nervous system. Its absence would make you develop nerve damages or some problems with your nerve conduction. More specifically, vitamin B12 can help generate myelin, a protective coating that can shield your nerves and help them transmit sensations. Without sufficient vitamin B12, it is impossible to coat the nerves, thus leading to nerve damages, especially in your feet and hands. That’s why you often feel tingling in those body parts. [2]
