Numbness is a broad term to describe an unusual sensation in any part of the body, but most commonly involving the hands and feet, sometimes including the arms and legs. Numbness may also be experienced around the mouth or in almost any part of the body. This numbing sensation may range from a tingling feeling, pins-and-needles sensation, to a complete lack of sensation or physical response to outer stimulus. Numbness may be harmless and temporary, such as when one is exposed to extremely cold temperatures, fingers will feel numb. One can also have episodes of numbness or tingling in the fingers and around the mouth when experiencing attacks of anxiety or even migraines. However, it may also be a sign of a serious condition, such as a nerve damage, which can become progressive and permanent.

Numbness may also be associated with burning sensation, sharp pains, or weakness of the arm, leg, or facial muscles. Depending on the cause or condition that causes this symptom, numbness may be a sign of a temporary condition or a serious disease. Causes of Numbness in Hands and Feet

According to experts, the most common cause of numbness in the hands and feet that results in complete lack of ability to feel or react to an external stimulus is nerve damage. However, there are many other physical and emotional factors that can cause a temporary, progressive or a permanent numbness in the hands and feet. Physical problems

• Nutritional deficiencies – A poor diet that is deficient in essential vitamins like A, B5, B6, B12, and D, and minerals like iron, calcium, potassium, sodium and phosphorus can lead to various symptoms, including numbness or tingling in the hands and feet. To determine if any of these nutritional deficiencies is the cause of numbness, blood tests may be done.

• Nerve compression – Numbness is a common sensation, accompanied by heaviness of the arm or leg, after a person sits or stands in the same position for a long time. This is caused by prolonged compression of a nerve, although the tingling or pins-and-needles sensation is often short lasting and relieved by a change in position. Repeated and prolonged nerve compression which results in nerve damage can cause a more serious problem that can lead to pain and weakness of the hands or feet. Examples include: a) Carpal tunnel syndrome – compression of the nerves of the wrist which commonly occurs in people who use computer keyboards for long periods, or those who use their hands and wrists repeatedly. b) Herniated disk or slipped disk – involves compression of spinal nerves that leads to pain and numbness of the back, legs, and feet. c) Traumatic compression of nerves – any traumatic event that may result in nerve compression and damage can lead to numbness and other symptoms in the hands and feet.

• Conditions that result in reduced blood circulation – Some conditions that are characterized by low blood perfusion can cause either temporary or permanent numbness in hands and feet. Low temperatures can constrict the blood vessels and cause numbness of the hands, feet, nose, and ears. People who suffer from Raynaud’s syndrome have a problem with circulation which causes them to feel numb when exposed to cold temperatures.

Emotional or psychological factors can also cause numbing of the hands and feet. Acute stress and anxiety can sometimes cause one to breathe fast or hyperventilate. Fast, shallow breathing for even a few minutes can cause tingling of the lips, hands, and feet, sometimes associated with stiffness and even fainting.
