Nerve damage to the disc in the spine

Any nerve damage to the discs in the back can lead to the leg and hand numbness. Once moved to a certain position, the herniated disc will add pressure on the nerves and create numbness. Any injury to the top part of the spine close to neck usually manifests as tingling and painful numbness or sensation in the hands or arms, while lower back injuries can affect the legs and feet.

Raynaud’s phenomenon

This is a circulatory condition that causes the extremities such as the ears, nose, finger and toes to tingle and go numb when exposed to cold or when the individual experiences extreme stress and emotions. The blood vessels constrict as a response and transmit a tingling sensation through the hands, numbing the extremity. This numbing sensation can persist for several minutes up to a few hours. Relaxation techniques can help prevent the attacks of numbness among individuals who suffer from this condition.
