Nerve injury is when a nerve stops transmission of signals from one side of the brain to the other, prevents muscles from working, and causes a loss of feeling in the area supplied by that nerve. There are three basic types of nerve injury. The first kind is where the nerve is bruised and does not work properly for a short period of time, but all the inner cables remain intact. This type of nerve injury recovers fully and leaves no deficit at all. The second kind is where the inner cables are damaged, but the outer layer remains intact. The third kind is where the nerve is divided, and both the outer layer and inner cables are divided. This type of injury requires the nerve to be repaired, if it is to recover.
Symptoms largely depend on the kind of nerve affected, and whether one nerve or several nerves, or the whole body has been affected. Numbness and pain. Tingling and burning in the arms and legs. Contraction of muscles. Lightheadedness and fainting. Chest discomfort or pain that points to heart disease.
The common causes of nerve injury are: Compression and stretching. Electrical Injury. Laceration. Diabetes. Drug injection injury. Focal contusion.
