Nerve Damage (Overview)

A complete nerve transection will leave an area totally numb. The distribution of the numbers depends upon where the nerve was cut. A partial nerve injury may leave the area tingly or incompletely numb. Finally even if the nerve is not cut the swelling and bruising to the tea can affect the nerve as well. Usually we consider sharp penetrating injuries as likely having nerve lacerations when sensation is lost. A hand surgeon can examine the hand and pinpoint the site or extent of nerve injury and recommend surgical repair if needed.

How long does nerve damage from B12 defeciancy take to heal?

How long does nerve damage from B12 defeciancy take to heal?

B12 nerve damage: Healing of nerves after vitamin B12 deficiency takes different amounts of time, depending on how severe and how long lasting the deficiency was. Nerves also heal slowly. They do not heal until after the B12 level is restored to normal. In my experience, recovery takes 2-3 months, although I have seen it take 12 months, and sometimes healing is not complete. Most cases have a good outcome. ...Read more

Can nerve damage heal?

Yes: If the damage does not cause the nerve to be completely cut, then healing can occur. If a nerve has been cut, it will need to be reconnected in order to grow. Nerve grows about 1 mm/day, so depending on where the injury is, it may take over a year for recovery. It is difficult after a nerve is cut to get 100% recovery, but some return of sensation can be expected after repair. ...Read more

Neuropraxia (Definition)

Neuropraxia is defined as a temporary loss of function of the nerve. Some nerves are purely sensory while others carry both sensory and motor fibers. Traumatic contusion injuries to nerves or nerve compressions can cause Neuropraxia.

Nerve (Definition)

The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
