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.
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.
Nerve function tests.
Electromyography (EMG) records electrical activity in your muscles to detect nerve damage. A thin needle (electrode) is inserted into the muscle to measure electrical activity as you contract the muscle.
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.
Signs and symptoms of peripheral neuropathy might include: Gradual onset of numbness, prickling or tingling in your feet or hands, which can spread upward into your legs and arms. Sharp, jabbing, throbbing or burning pain.
Symptoms of peripheral neuropathy
numbness and tingling in the feet or hands. burning, stabbing or shooting pain in affected areas. loss of balance and co-ordination. muscle weakness, especially in the feet.
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.
Nerves recover slowly, and maximal recovery may take many months or several years. You'll need regular checkups to make sure your recovery stays on track. If your injury is caused by a medical condition, your doctor will treat the underlying condition.
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.
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.
Nerve conditions can be hard to diagnose, and many patients live for years without an explanation or effective treatment for their muscle weakness or pain. Our specialists understand that the cause of a nerve condition is not always obvious and often requires a bit of detective work to uncover.
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.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
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.
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.
Multimodal therapy (including medicines, physical therapy, psychological counseling and sometimes surgery) is usually required to treat neuropathic pain. Medicines commonly prescribed for neuropathic pain include anti-seizure drugs such as: Gabapentin (Neurontin®). Pregabalin (Lyrica®).
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.
Schwann cells can help damaged nerves regenerate and restore function. On average, damaged nerves can grow back at a rate of about 1 inch per month or 1 millimeter per day. Surgery is needed if there is significant scar tissue or a gap between cut nerve ends.
Neurologists are specialists who treat diseases of the brain and spinal cord, peripheral nerves and muscles.
One of the first symptoms of nerve damage can be sensitivity, which manifests as sharp, lightning-like pain, burning and throbbing pain, or stabbing pain. Sensitivity is one common symptom of nerve damage that can occur when your nerves cannot send or relay messages accurately.
Common causes of neuropathic pain include nerve pressure or nerve damage after surgery or trauma, viral infections, cancer, vascular malformations, alcoholism, neurological conditions such as multiple sclerosis and metabolic conditions such as diabetes. It may also be a side effect of certain medications.
Whether or not neuropathy can be reversed depends on the cause of the nerve damage. In some cases, the pain may go away entirely. In others, nerve damage may be permanent. For example, when neuropathy is caused by an infection, symptoms might go away completely when the infection is treated.
Massage therapy can be beneficial if you have neuropathy — numbness, tingling or pain — in your hands and feet. This is particularly common in cancer survivors.
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.
