Nerve injuries in the cervical spine area are very difficult to recover from. In the case of milder cervical spine nerve injuries, such as more minor contusions and more minor compression injuries, it is expected that the vast majority of function will be restored with neurotrophic therapy, but it may not be 100% restored. If the cervical nerve is a very serious injury, or even if the cervical nerve is severed, even if the nerve is successfully sutured back together through surgery, the nerve is basically difficult to recover. Even if the nerve is restored, only a very small portion of the function can be restored, mainly due to the special characteristics of the nerve. Nerve cells are non-renewable cells, and there is no way to regenerate them once they are damaged.
