Nerve Injuries

Also known as: peripheral nerve injuries.

What are nerve injuries?

Nerves are the system of fibers that carry signals to and from the brain and the rest of the body. When an injury or damage occurs to one or many nerves, these are known as nerve injuries.


What causes nerve injuries?

Causes of peripheral nerve injury include:

  1. Compression—too much pressure on the nerve (from surrounding scar tissue or swollen muscles)
  2. Crush/percussion injury (from bone fractures or gunshot wounds)
  3. Laceration (a cut or tear in the nerve, usually from penetrating trauma)
  4. Stretch injury (usually from traction on a limb)
  5. Electrical injury
  6. Frostbite injury
  7. Toxins (sugar, alcohol, heavy metals, infections)


What are the symptoms of nerve injuries?

Weakness/paralysis, numbness, pain, loss of sensation and loss of function are all possible symptoms of nerve injury.


What are nerve injury care options?

Some minor nerve injuries can heal themselves through rest of the affected area. More severe nerve injuries may require surgery. In many cases, rehabilitation is needed in order to facilitate full recovery.
