Explanation

The peripheral nervous system is a network of 43 pairs of motor and sensory nerves that connect the brain and spinal cord (the central nervous system) to the entire human body. These nerves control the functions of sensation, movement, and motor coordination. They are fragile and can be damaged easily. Injury to the peripheral nerve network can happen through: Laceration (a cut or tear in the nerve tissue), Severe bruising (contusion), Gunshot wounds, Stretching (traction), Drug injection injury, Electrical injury, etc. People with traumatic nerve damage can experience severe, unrelenting pain, burning sensation, tingling, or total loss of sensation in the part of the body affected by the damaged nerve.
