Yes, nerve injuries can heal; however, the rate and completeness of recovery vary depending on the injury’s severity and other factors. Although nerve regeneration is possible, it’s a slow process at approximately one inch monthly.

A more detailed explanation is provided below:

Nerve Regeneration:

Following nerve injury, axons undergo retraction before regenerating and attempting reconnection to their target.

Factors Affecting Healing:

Mild nerve injuries, with intact protective sheaths, usually heal without intervention. Severe injuries such as severed nerves might necessitate surgery, with uncertain recovery.

Nerve Regeneration Time:

The more distant the injury site from the innervated tissue, the extended the nerve regrowth and functional recovery period.

Age: Younger patients tend to experience better nerve regeneration than older patients.

Wallerian Degeneration: Nerve injury causes the distal portion of the nerve to degenerate.

Axonal Regeneration: Nerve fiber regeneration starts, growing towards the target tissue.

Reinnervation: Nerve fibers regenerate and reconnect to the target tissue, thus restoring function.

Treatment:

Mild nerve injuries may be treated without surgery using medication, physical therapy, or massage.

Surgical: Severe injuries may require surgery to repair or reconstruct the damaged nerve.

To repair a severed nerve, a nerve graft may be necessary to connect the two severed ends.

Recovery Time:

Nerve recovery is slow, potentially taking months or even years for full healing.
