Nerves are the bodys networking system that carries messages between the brain and the rest of the body. Nerve injury is injury to nervous tissue. Nerves are fragile and can be damaged by pressure, stretching, or cutting. Injury to a nerve can stop signals to and from the brain, causing muscles not to work properly, and a loss of feeling in the injured area.
The signs and symptoms of nerve injuries can be different depending on the nerve injured, the type of injury, and the severity of the injury. Some may include:
Some nerves only transmit sensation, so a nerve injury to these nerves would
cause some amount of numbness
Weakness: In addition to sensory nerves, some nerves give you the ability to move, and other nerves do both of these things. Injury to nerves that carry motor signals causes some amount of weakness.
Pain: This is frequently a symptom after nerve injury. The pain present after a nerve injury can be anywhere along the course of the nerve, but it is typically at the injury site
