Nerve pain often feels like a shooting, stabbing or burning sensation. Sometimes it can feel as sharp and sudden as an electric shock. You may be very sensitive to touch or cold.
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.
Trigeminal neuralgia (TN), also known as tic douloureux, is sometimes described as the most excruciating pain known to humanity. The pain typically involves the lower face and jaw, although sometimes it affects the area around the nose and above the eye.
Neuropathic pain can feel excruciating to your raw nerves, especially when you're tired.
Nerve pain can occur without nerve damage. For example, idiopathic nerve pain and temporary paresthesia are not caused by nerve damage. Idiopathic nerve pain is nerve pain without an identifiable cause. Temporary paresthesia is short-term nerve pain that results from temporary pressure on a nerve or poor circulation.
An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.

Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
One of the classic examples of neuropathic pain is Tic douloureux. Without treatment, this is a debilitating disorder that involves attacks of severe pain in the facial area (also referred to as trigeminal neuralgia).
The most common cause of nerve damage is diabetes. Diabetes can damage the nerves by causing them to swell and press against blood vessels. Since sensory nerves are the most likely to be affected, this can cause a loss of sensation or weakness in the affected area.
Damage to the nerves can make it harder to control muscles. It can also cause weakness. You may notice problems moving a part of your body. You may fall because your legs buckle.
The pressure affects the nerve's function and triggers symptoms ranging from sharp pain and numbness of the skin to weakness and tingling. If left untreated, a pinched nerve can cause severe complications, including permanent nerve damage.
The abnormal pressure pushes on nerves and compresses the blood vessels that supply them. The nerves react to their distress by sending signals that cause an unpleasant, even painful, tingling sensation.
Each peripheral nerve is in itself complex; it has a very dedicated role relating to its own particular area of the body. Once this is damaged it is difficult to treat it because of the complexity of the nervous system.
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.
Numbness or decreased sensation in the area supplied by the nerve. Sharp, aching or burning pain, which may radiate outward. Tingling, pins and needles sensations (paresthesia) Muscle weakness in the affected area.
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.
Ten of the most common types of nerve pain include the following: Peripheral neuropathy involves damage to the peripheral nervous system (nerves outside the brain and spinal cord). Pain may be felt in the feet, legs, arms, hands, or other areas of the body. There are more than 100 types of peripheral neuropathy.
An EMG test helps find out if muscles are responding the right way to nerve signals. Nerve conduction studies help diagnose nerve damage or disease. When EMG tests and nerve conduction studies are done together, it helps providers tell if your symptoms are caused by a muscle disorder or a nerve problem.
Electromyography (EMG) is used to record the electrical activity in muscle. It can identify abnormalities in the muscles or nerves resulting from peripheral neuropathy, nerve degeneration or damage to the protective covering (myelin sheath) that surrounds the nerves in your brain or spinal cord.
Stage Three: The Pain Reaches Its High Point
This pain is so great that it's impacting your life in a number of negative ways. You may have tried several pain medications, but discovered that they don't help. You're also likely suffering from the other symptoms of nerve damage.
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.
