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.
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.
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.
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.
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. Autoimmune diseases including lupus, rheumatoid arthritis and Sjogren's syndrome.
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.
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.
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.
Electromyography (EMG).
During an EMG , your doctor inserts a needle electrode through your skin into various muscles. The test evaluates the electrical activity of your muscles when they contract and when they're at rest. Test results tell your doctor if there is damage to the nerves leading to the muscles.
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.
1.1.
Seddon2 classified nerve injuries into three broad categories; neurapraxia, axonotmesis, and neurotmesis.
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.
Nerve Pain
It's best to use cold when the pain is still sharp and move on to heat once that sharpness has subsided. The heat will increase blood flow and help tissues heal faster.
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.
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.
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.
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.
Numerous clinical studies have found that magnesium has beneficial effects in patients suffering from neuropathic pain, dysmenorrhea, tension headache, acute migraine attack, and others.
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.
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.
Capsaicin is used to help relieve a certain type of pain known as neuralgia (shooting or burning pain in the nerves). Capsaicin is also used to help relieve minor pain associated with rheumatoid arthritis or muscle sprains and strains.
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.
