If a nerve is injured but not cut, the injury is more likely to heal. Injuries in which the nerve has been completely severed are very difficult to treat, and recovery may not be possible. Your doctor will determine your treatment based on the extent and cause of your injury and how well the nerve is healing.
Some nerve-related problems do not interfere with daily life. Others get worse quickly and may lead to long-term, severe symptoms and problems. When a medical condition can be found and treated, your outlook may be excellent. But sometimes, nerve damage can be permanent, even if the cause is treated.
If the underlying cause of peripheral neuropathy isn't treated, you may be at risk of developing potentially serious complications, such as a foot ulcer that becomes infected. This can lead to gangrene (tissue death) if untreated, and in severe cases may mean the affected foot has to be amputated.
A nerve injury can affect the brain's ability to communicate with muscles and organs. Damage to the peripheral nerves is called peripheral neuropathy. It's important to get medical care for a peripheral nerve injury as soon as possible. Early diagnosis and treatment may prevent complications and permanent damage.
If the nerve is mildly pinched but still functional, then it can recover function in a few hours or a few days. As the nerve compression gets more severe or if it has been compressed a long time, it can take months for nerves to improve. The nerve will regenerate better in younger patients than in older patients.
Injured nerve cells in the central nervous system typically do not regenerate. However, this part of the nervous system can reorganize in response to an injury. This is called "plasticity." Luckily, the brain has a lot of built-in redundancy.
Nerve grafting – taking a sensory nerve from another part of the body, or from a donor, and suturing it into the damaged nerve to help it to regenerate. Nerve transfer – using a small part of a functional nerve to connect to and salvage muscle function when a nerve is too damaged to be repaired.
Peripheral neuropathy, a result of damage to the nerves located outside of the brain and spinal cord (peripheral nerves), often causes weakness, numbness and pain, usually in the hands and feet. It can also affect other areas and body functions including digestion, urination and circulation.
CT or MRI scans can look for herniated disks, pinched (compressed) nerves, tumors or other abnormalities affecting the blood vessels and bones. Nerve function tests. Electromyography (EMG) records electrical activity in your muscles to detect nerve damage.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
The outlook for peripheral neuropathy varies, depending on the underlying cause and which nerves have been damaged. Some cases may improve with time if the underlying cause is treated, whereas in some people the damage may be permanent or may get gradually worse with time.
In many instances, nerve damage cannot be cured entirely. But there are various treatments that can reduce your symptoms. Because nerve damage is often progressive, it is important to consult with a doctor when you first notice symptoms. That way you can reduce the likelihood of permanent damage.
Trauma. Trauma, such as a car accident or a fall, can damage the nerves by crushing them. This can cause a loss of sensation or weakness in the affected area. In some cases, nerves can also be crushed, or compressed, by other factors such as surgery, herniated discs, carpal tunnel syndrome, or bone spurs.
Types of nerve damage
The most severe type of nerve injury is an avulsion (A), where the nerve roots are torn away from the spinal cord. Less severe injuries involve a stretching (B) of the nerve fibers or a rupture (C), where the nerve is torn into two pieces.
You're normally under general anesthesia for nerve repair surgery, so you'll feel no pain during the procedure. Your surgeon examines the injured nerve using a powerful microscope and debrides torn tissue or scar tissue from the ends.
Chronic stress can lead to neuropathy by damaging the nervous system. When the nervous system is damaged, it can cause pain, numbness, tingling, and other symptoms. The end result is pain, discomfort, or even worse.
Nerve Cells Do Not Renew Themselves
After an injury, the skin makes a bunch of new cells and uses them to heal your wound. Yet, nerve cells in your brain, also called neurons, do not renew themselves. They do not divide at all.
Does an MRI scan show nerve damage? A neurological examination can diagnose nerve damage, but an MRI scan can pinpoint it. It's crucial to get tested if symptoms worsen to avoid any permanent nerve damage.
Peripheral nerve injuries are fairly common ailments. They can be caused by sports injuries, trauma such as a vehicle accident or a fall, or overuse. Our board-certified orthopedic surgeons and the medical team at Coastal Empire Orthopedics treat many patients with nerve injuries.
Nerve damage can cause pain, numbness, tingling or burning sensations that feel like electric shocks, and weakness in the affected area. Nerve damage can lead to several side effects, including skin sores and loss of sensation, which lead to permanent issues if the underlying cause goes unaddressed.
A variety of blood tests may be performed to determine the cause of nerve damage. These tests may look for high blood glucose levels, diabetes onset, vitamin deficiencies, etc.
Identifying the cause of a neuropathy
The GP can usually identify the underlying cause of a peripheral neuropathy. If diabetes is suspected, they can usually make a confident diagnosis based on your symptoms, a physical examination, and checking the levels of sugar in your blood and urine.
