Vitamin B12 is an essential nutrient that plays an important role in maintaining overall health, especially for the nervous system and red blood cell production.
Vitamin B12 deficiency often comes from an unscientific diet, absorption problems or certain medical conditions.
Here are some symptoms in the feet that may be due to vitamin B12 deficiency:
Itchy feet
A common early sign of vitamin B12 deficiency is a tingling sensation in the legs, known as a cold. You may find that feeling itchy or numb at night will affect your sleep quality.
Weakness and fatigue
Feeling weak, tired, and decreased staminality in physical activities is another sign of vitamin B12 deficiency.
When fatigue gets worse at night, the body is weak, making it difficult for you to sleep well, consult a health care professional and promptly supplement vitamin B12.
Stroke and muscle pain
People with vitamin B12 deficiency at night often have problems such as cramps and muscle pain in their legs, which makes you feel uncomfortable and hinders your sleep.
Unusual pain in the legs can stem from nerve damage caused by a long-term vitamin B12 deficiency, affecting muscle function.

Difficulty walking
Having difficulty walking or walking unsteadily can be an alarming symptom of vitamin B12 deficiency. These problems often arise from nerve damage that affects your ability to coordinate and maintain balance.
If you find it difficult to walk or balance, you should seek medical advice.
