Top 8 Symptoms of B12 Deficiency in Females

3. Pins and Needles

Many people experience the sensation of pins and needles when sitting cross-legged or resting on an arm. Commonly, this natural phenomenon is referred to as the body part in question "falling asleep." However, strange sensations, like electrified pinches, throughout the body with no obvious cause may indicate a B12 vitamin deficiency. Some patients report a feeling as if an electrical current is running from their fingers up their arms. Any type of tingling or numbness in the body can be a symptom of nerve damage. It may be a result of lack of oxygen in the red blood cells, which may indicate lack of vitamin B12.
