Left untreated, nerve damage may worsen over time. It can sometimes start in the nerves farthest from the brain and spinal cord -- like those in the feet and hands. Then it may move up into the legs and arms.
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.
On average, a pinched nerve can last from as little as a few days to as long as 4 to 6 weeks — or, in some cases, even longer (in which case you should see your doctor).
The signs of nerve damage
Numbness or tingling in the hands and feet. Feeling like you're wearing a tight glove or sock. Muscle weakness, especially in your arms or legs. Regularly dropping objects that you're holding.
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.
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.
As a specialist in peripheral nerve surgery, Dr. Seruya wants his patients to know that after a period of 12-18 months nerve damage can become permanent.
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.
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.
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.
Nerve cells can regenerate and grow back at a rate of about an inch a month, but recovery is typically incomplete and slow. This is a complete nerve injury, where the nerve sheath and underlying neurons are severed. If there is an open cut, a neurosurgeon can see the cut nerve ends at surgery and repair this.
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.
The pain, tingling, numbness and other discomforts of peripheral nerve disorders can often be treated successfully with physical therapy and other nonsurgical methods. But in some cases, surgery offers the best chance of lasting relief.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
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.
Nerve damage is known to cause some of the worst pain a human being can experience, along with disability that can result in an inability to work temporarily or permanently. However, proving in a personal injury case that disabling nerve damage has occurred can be difficult.
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.
People with nerve pain feel it in different ways. For some, it's a stabbing pain in the middle of the night. For others, symptoms can include a chronic prickling, tingling, or burning they feel all day.
Neurologists are specialists who treat diseases of the brain and spinal cord, peripheral nerves and muscles.
The main medicines recommended for neuropathic pain include: amitriptyline – also used for treatment of headaches and depression. duloxetine – also used for treatment of bladder problems and depression. pregabalin and gabapentin – also used to treat epilepsy, headaches or anxiety.
If left untreated, the numbness, tingling, and burning caused by peripheral neuropathy will get worse over time. The damaged nerves will continue to send confusing messages to the brain more frequently until the spinal cord gets so used to sending the signals, it will continue to do it on its own.
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.
Over time, those fibers may undergo degeneration and die, which means the neuropathy is worse because of the loss of more nerve fibers. This may cause increased numbness, but it usually causes the pain to get better. In this scenario, less pain means greater degeneration.
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.
