Since peripheral nerves are found throughout the body, nearly any type of injury can result in damage to one or more peripheral nerves. Nerves may be severed, stretched, contused, blown apart, crushed, torn, or avulsed from the spinal cord. The type of treatment and timing of treatment depend entirely upon the mechanism of injury. For example, some injuries are best treated immediately; some require a period of observation lasting weeks to months, so that spontaneous recovery can occur without the need for surgery.
That is why it is so important to see a specialist in peripheral nerve surgery as soon as possible after your injury occurs. That way, you will not suffer the frustration of having a permanent disability because it is too late to repair your peripheral nerve injury.
