What Is Neuropathy and How Is It Treated?
Peripheral neuropathy has many potential causes. Diagnosis includes a physical exam, possible blood tests, and usually requires:
A full medical history. Your doctor will review your medical history, including your symptoms, your lifestyle, exposure to toxins, drinking habits and a family history of nervous system (neurological) diseases.
Neurological examination. Your doctor might check your tendon reflexes, your muscle strength and tone, your ability to feel certain sensations, your posture and your coordination.
Tests
Your doctor may order tests, including:
Blood tests. These can detect vitamin deficiencies, diabetes, abnormal immune function and other indications of conditions that can cause peripheral neuropathy.
Imaging tests. CT or MRI scans can look for herniated disks, tumors or other abnormalities.
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.
At the same time as an electromyogram, your doctor or an EMG technician typically performs a nerve conduction study. Flat electrodes are placed on the skin and a low electric current stimulates the nerves. Your doctor will record your nerves' responses to the electric current.
Other nerve function tests. These might include an autonomic reflex screen that records how the autonomic nerve fibers work, a sweat test that measures your body's ability to sweat, and sensory tests that record how you feel touch, vibration, cooling and heat.
Treatment
The goal of treating neuropathy is to manage the condition causing it and to relieve symptoms. If your lab tests indicate no underlying condition(s), your doctor may recommend watchful waiting, to see if the neuropathy improves.
Medications
There are medications used to relieve peripheral neuropathy signs and symptoms and there are medications used to treat conditions associated with the peripheral neuropathy. These include:
Pain relievers. Over-the-counter pain medications, such as nonsteroidal anti-inflammatory drugs, can relieve mild symptoms. For more-severe symptoms, your doctor might prescribe painkillers.
Medications containing opioids, such as tramadol (Conzip, Ultram) or oxycodone (Oxycontin, Roxicodone, others), can lead to dependence and addiction, so these drugs generally are only prescribed when other treatments fail.
Anti-seizure medications. Medications such as gabapentin (Gralise, Neurontin, Horizant) and pregabalin (Lyrica), developed to treat epilepsy, may relieve nerve pain. Side effects can include drowsiness and dizziness.
Topical treatments. Capsaicin cream, which contains a substance found in hot peppers, can cause modest improvements in peripheral neuropathy symptoms. You might have skin burning and irritation where you apply the cream, but this usually lessens over time. In rare instances, it is not tolerated.
Lidocaine patches are another treatment you apply to your skin that might offer pain relief. Side effects can include drowsiness, dizziness and numbness at the site of the patch.
Antidepressants. Certain tricyclic antidepressants, such as amitriptyline, doxepin (Silenor, Zonalon) and nortriptyline (Pamelor), have been found to help relieve pain by interfering with chemical processes in your brain and spinal cord that cause you to feel pain.
The serotonin and norepinephrine reuptake inhibitor duloxetine (Cymbalta) and the extended-release antidepressant venlafaxine (Effexor XR) also might ease the pain of peripheral neuropathy caused by diabetes.
Side effects of antidepressants may include dry mouth, nausea, drowsiness, dizziness, decreased appetite and constipation.
Therapies
Various therapies and procedures might help ease the signs and symptoms of peripheral neuropathy.
Transcutaneous electrical nerve stimulation (TENS). Electrodes placed on the skin deliver a gentle electric current at varying frequencies. TENS should be applied for 30 minutes daily for about a month.
Plasma exchange and intravenous immune globulin. These procedures, which help suppress immune system activity, might benefit people with certain inflammatory conditions.
Plasma exchange involves removing your blood, then removing antibodies and other proteins from the blood and returning the blood to your body. In immune globulin therapy, you receive high levels of proteins that work as antibodies (immunoglobulins).
Physical therapy. If you have muscle weakness, physical therapy can help improve your movements. You may also need hand or foot braces, a cane, a walker, or a wheelchair.
Surgery. If you have neuropathies caused by pressure on nerves, such as pressure from tumors, you might need surgery to reduce the pressure.
SCS. Spinal cord stimulation implant to disrupt the pain signals to the brain.
Alternative Medicine
Some people with peripheral neuropathy try complementary treatments for relief. Although researchers haven't studied these techniques as thoroughly as they have most medications, the following therapies have shown some promise:
Acupuncture. Inserting thin needles into various points on your body might reduce peripheral neuropathy symptoms. You might need multiple sessions before you notice improvement. Acupuncture is generally considered safe when performed by a certified practitioner using sterile needles.
Herbs. Certain herbs, such as evening primrose oil, might help reduce neuropathy pain in people with diabetes. Some herbs interact with medications, so discuss herbs you're considering with your doctor.
Amino acids. Amino acids, such as acetyl-L-carnitine, might benefit people who have undergone chemotherapy and people with diabetes. Side effects might include nausea and vomiting.
Lifestyle and Home Remedies
To help manage your peripheral neuropathy:
Take care of your feet, especially if you have diabetes. Check daily for blisters, cuts or calluses. Wear soft, loose cotton socks and padded shoes. You can use a semicircular hoop, which is available in medical supply stores, to keep bed covers off hot or sensitive feet.
Exercise. Regular exercise, such as walking three times a week, can reduce neuropathy pain, improve muscle strength and help control blood sugar levels. Gentle routines such as yoga and tai chi might also help.
Quit smoking. Cigarette smoking can affect circulation, increasing the risk of foot problems and other neuropathy complications.
Eat healthy meals. Good nutrition is especially important to ensure that you get essential vitamins and minerals. Include fruits, vegetables, whole grains and lean protein in your diet.
Avoid excessive alcohol. Alcohol can worsen peripheral neuropathy.
Monitor your blood glucose levels. If you have diabetes, this will help keep your blood glucose under control and might help improve your neuropathy.
