Causes    TOP

This pain may be caused by hurt nerve fibers that send pain signals to your brain. This can happen even when there is no event to start the pain. For example, a person with neuropathic pain may have a feeling of pins and needles when putting on socks.

Nerve damage may be from:

  • Physical damage
  • Chemicals
  • The nerve not getting the vital nutrients needed to work
  • Infection
  • The body’s immune system attacking the nerves

Sometimes the cause of the nerve pain is unknown.

Risk Factors    TOP

Certain health problems raise your risk of getting neuropathic pain, such as:

It may also be raised due to:

  • Back surgery
  • Chemotherapy
  • Being around toxins or metals
  • Certain medicines

Symptoms    TOP

Neuropathic pain may cause feelings of:

  • Burning
  • Stabbing
  • Electrical shock
  • Pins and needles/tingling
  • Numbness

This pain may be all the time or come and go during the day. The pain can get in the way of daily activities like sleep. In some cases, even the touch of a bed sheet can cause pain.

Diagnosis    TOP

Your doctor will ask about your symptoms and health history. A physical exam will be done.

You may be sent to a neurologist to be checked or treated.

You may also be referred to a special doctor who can help you take care of your pain.

Treatment    TOP

Talk with your doctor about the best plan for you. You may have:

Medications

There are a number of medicines that can help treat neuropathic pain. Some of these were made to treat other health problems. They have also been found to be useful for treating nerve pain.

Medicines to treat symptoms of peripheral neuropathy:

  • Antiseizure medicine
  • Antidepressants
  • Opioid pain relievers
  • Over the counter pain relievers, such as ibuprofen
  • Topical creams put on the skin or patches, such as capsaicin cream

It may take a while for your doctor to find the right medicine for you. You may need to take more than one medicine.

Herbals

In recent years, some states have approved marijuana for certain health problems. Some studies support using it for spasticity. Talk to your doctor about whether it is right for you. Find out whether it is a legal option where you live.

Other Options    TOP

  • Ask your doctor to suggest a safe exercise program. Being active will help your health.
  • Work with a therapist to help cope with pain. Joining a support group may also be helpful.
  • Talk to your family and friends about your health problem. They can offer help and support.
  • Learn relaxation techniques, such as meditation, to lower stress.
  • If you have another health problem, like diabetes, be sure to get care for it.

Procedures    TOP

Your doctor may advise nerve decompression. If pressure on the nerve is causing pain, surgery can relieve it. This can help lower the pain or make it go away.

If you are still not feeling better, your doctor may advise:

  • A nerve block—An anesthetic is injected into the painful site to block pain.
  • Pain pump—A pain pump can be placed in your body to give you pain medicine.
  • Nerve stimulators—This device is attached to the nerve and gives electrical signals to control pain.
  • Surgery can be done to block the hurt nerves from sending signals.

Prevention    TOP

You can lower your chance of getting neuropathic pain by getting care for any health problems, such as diabetes.
