Tingling, Numbness, or Strange Nerve Sensations
A pins and needles feeling in your hands often points to B12 deficiency. This happens because B12 protects the protective coating around your nerves. Without enough B12, nerve signals become slower and less reliable over time. Some people also notice numbness spreading into their feet or legs. Others describe a burning or prickling sensation that comes and goes. This symptom should never be ignored for long periods of time. Nerve damage can become permanent if deficiency continues without treatment.
