Peripheral nerves can be damaged in several ways: Injury from an accident, a fall or sports, which can stretch, compress, crush or cut nerves. Medical conditions, such as diabetes, Guillain-Barre syndrome and carpal tunnel syndrome.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
Nerve conduction studies, including an Electromyogram (EMG) may be performed on individuals suffering with nerve pain symptoms. These studies use electrical impulses to determine the level of damage. A final diagnosis will be made by your physician through the help of one or all of these tests.
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 pain often feels like a shooting, stabbing or burning sensation. Sometimes it can be as sharp and sudden as an electric shock. People with neuropathic pain are often very sensitive to touch or cold and can experience pain as a result of stimuli that would not normally be painful, such as brushing the skin.
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.
Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of 'rest' following your injury.
Diabetes. This is the most common cause. Among people with diabetes, more than halfwill develop some type of neuropathy.
In the closed claims database study, ulnar neuropathy is the most common lesion representing 28% of all peripheral nerve injury claims, followed by the brachial plexus (20%), lumbosacral nerve root (16%), and spinal cord (13%).
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.
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.
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.
Nerve damage can be extremely debilitating and could result in permanent disabilities. The impact of nerve damage could range from numbness to chronic pain or even paralysis.
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.
People with traumatic nerve damage can experience severe, unrelenting pain, burning sensation, tingling or total loss of sensation in the part of the body affected by the damaged nerve.
Magnesium promotes the regeneration of the peripheral nerve.
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.
Answer: Damaged nerves cannot be seen on a regular X-ray. They can be seen on CAT scan or MRI, and in fact, MRI is recommended for examining details of the spinal cord. For example, MRI can demonstrate tumors of the spinal cord and nerves that extend from the spinal cord called nerve roots.
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.
Neurapraxia is the mildest form of peripheral nerve injury commonly induced by focal demyelination or ischemia. In neurapraxia, the conduction of nerve impulses is blocked in the injured area. Motor and sensory conduction are partially or entirely lost.
Walk it off. Exercise releases natural painkillers called endorphins. Exercise also promotes blood flow to the nerves in the legs and feet. Researchers believe that regular exercise may create a long-lasting expansion in blood vessels in the feet, nourishing damaged nerves back to health.
