One medical portal reports a case of vitamin B12 deficiency in a 62-year-old man. Because of this, he developed tingling in the body, difficulty walking, severe pain in the joints, shortness of breath, yellowing of the skin.
According to Dr. Ioannis Liakas, one of the important signs of a B12 deficiency is numbness in the hands and feet, tingling in them. As the NHS adds, this symptom is also known as paresthesia. At the same time, the feeling of tingling or numbness is similar to the fact that you have needles or pins under your skin.
