Nerves are the wires that allow the brain to communicate with the body. When you feel a sensation, it is your nerves telling communicating to your brain what you are feeling. Once damaged, injury stops nerves from getting sent signals from your brain, telling them to experience sensations, meaning that your injured nerves and your brain have stopped communicating. Nerve damage can occur as a result of an injury or underlying medical condition. It can primarily occur in your arms, feet and hands, however, it can also occur in other areas of the body. Common instances of injury can occur when the finger, hand or wrist is injured, such as being over stretched, burned, crushed, cut or too much pressure is applied. Car accidents, work-related injuries and falls are common causes of nerve damage. Whilst some nerves can heal themselves, severe trauma to nerves can permanently damage them, sometimes resulting in a loss of hand movement.
The symptoms of nerve damage range from minor to severe, such as numbness, difficulty moving the hand or wrist, a burning sensation, pain, loss of movement in the hand or wrist, twitching and weakness.
