Nerves do not necessarily repair themselves. Some nerves can repair themselves, while others cannot, and need to be analyzed on a case-by-case basis. 1. It is related to the type of nerve injured, the cause, degree and duration of the injury. If the nerve damage is minor, not to the neurons, ganglia, or due to nerve edema and other reasons caused by a transient injury, can be repaired by itself. 2, if the nerve break or damage to the ganglia, the possibility of self-repair is very small. 3, if it is a complete spinal nerve injury, generally may not recover, but the nerve repair is a longer process, through the self-repair system of immune cells The nerve repair is a longer process, through the self-repair system of immune cells or stem cells, coupled with the body’s self-metabolism, minor nerve damage can be slowly recovered, so it is not necessarily.
