A nerve conduction velocity (NCV) test — also called a nerve conduction study (NCS) — measures how fast an electrical impulse moves through your nerve. NCV can identify nerve damage. During the test, your nerve is stimulated, usually with electrode patches attached to your skin.
Your nerves transmit sensory (feelings of touch, pressure or temperature) and motor (movement of muscles) impulses to and from your brain. Damage to nerves may result in reduction or a complete loss of sensation, weakness and dry skin.
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.
Your surgeon can remove the damaged section and reconnect healthy nerve ends (nerve repair) or implant a piece of nerve from another part of your body (nerve graft). These procedures can help your nerves regrow.
The signs of nerve damage include the following: 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.
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 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.
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.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
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.
Roughly 20 million Americans are living with neuropathy. Living with daily pain and discomfort can be challenging. People with neuropathy are at a higher risk for depression and anxiety than those without a neurological disorder. The good news is treatable, and a pain management specialist can help.
Without proper treatment, a pinched nerve can develop into more serious conditions such as peripheral neuropathy or disc degeneration. You may also have general illness and chronic pain as a result of an untreated pinched nerve.
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.
The test involves lightly and briefly (1-2 seconds) touching the tips of the first, third and fifth toes of both feet with the index finger to detect a loss in sensation, and can be performed by patients and relatives alike in the comfort of their own home.
Depending on the extent of damage to the nerve, it can heal on its own or become permanent, even with treatment. If you suffer from a condition that causes nerve damage that is so severe that it impacts your ability to work for at least a year, you may be eligible to receive Social Security Disability benefits.
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.
Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings. The MRI scan images are obtained with a magnetic field and radio waves.
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).
Numerous clinical studies have found that magnesium has beneficial effects in patients suffering from neuropathic pain, dysmenorrhea, tension headache, acute migraine attack, and others.
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.
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.
Vitamins B-1, B-6, and B-12 have been found to be especially beneficial for treating neuropathy. Vitamin B-1, also known as thiamine, helps to reduce pain and inflammation and vitamin B-6 preserves the covering on nerve endings.
See a doctor right away if you have any of the following symptoms. You feel numbness, tingling, or burning. This sensation is an early sign of nerve damage, and may radiate from your hands or feet into your arms or legs, per the U.S. National Library of Medicine.
Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
