Thank you for your question. My answer is "No."
However, an injury to the cervical spinal nerves or those even lower, like an injury to the axillary (armpit) nerves or those in the elbow region can cause the symptoms of a pinched nerve with pain in the wrist. Pain would be located at the nerve injury or down the limb from the injured nerve. The only way a wrist injury could possibly cause a pinched nerve to your cervical region is if your wrist injury caused you to hold your wrist in a position that would strain your neck and pinch the nerves there. Very difficult to do.
One type of damage a cervical injury can cause is paralysis, or the loss of one's ability to move. This type of injury can also cause fractures, or cracks in one's bones.
The most common cause of cervical spine injury is a motor vehicle accident. Other possible causes are falls, sports, or penetrations such as stabbing or gunshots.
One cause of an ergonomic injury could be typing at a keyboard with improper posture or positioning. The improper technique could cause carpal-tunnel, the ergonomic injury.
It depends on how serious the injury is. It could cause sickness, stress, and if the damage is severe, it could cause death.
Overuse of muscles and tendons in certain areas of the body could cause a repetitive injury. This could be related to your occupation or a leisure activity that you frequently engage in.
Perhaps it is for protection, since an injury of the thoracolumbar area could cause death, but since the nerve arises from the cervical area and enters the thorax and then goes to the diaphragm, it stands a lesser chance of being injured.
It could spread to other parts of body & cause death.
If you are doing a sport you could fall or hurt yourself
A bad head injury could cause long term mental illness, due to brain damage.
Acquired brain injury (ABI) is characterised as a brain injury which has occurred after birth, and is not the cause of any genetic or congenital disorder. A "mild" ABI could be considered as a brain injury which does not have a profound impact on the brain functioning or the sufferers behaviour, or could be considered as temporary.
If the injury is to the area of the speech center in the brain, yes. Injury to other areas could also cause slow speech development under the right circumstances.
Running with an injury can be dangerous. Depending on the severity and location of the injury, you could cause further damage by running without allowing time for the injury to heal.
