What is Peripheral Neuropathy?

Peripheral neuropathy refers to the conditions that result when nerves that carry messages to and from the brain and spinal cord from and to the rest of the body are damaged or diseased. The peripheral nerves make up an intricate network that connects the brain and spinal cord to the muscles, skin, and internal organs.

Neuropathy causes tingling or numbness, especially in the hands and feet. It affects about one to two percent of Americans and is caused by damage to single or multiple nerves. There are different types, but peripheral neuropathy is the most common in those with diabetes.

Symptoms are often ignored by both patients and health care professionals. If you have symptoms of neuropathy, it is important to discuss this with your health care team as soon as possible

Symptoms of Neuropathy

Peripheral neuropathy can affect the nerves that tell you the position of your hands or feet that let you sense hot or cold or that senses pain. You can experience a tingling or numbness in certain areas of the body, commonly the hands and feet. These sensations can range from mild to painful and are almost always greatest at night.

Common signs and symptoms include:

  • Numbness or tingling, especially of the hands or feet.
  • Pain or cramping, especially of the hands, feet or calf muscles.
  • Sensitivity to touch or temperature.
  • Loss of reflexes.
  • Muscle wasting in the hands and feet.
  • Weakness, especially in the feet or hands.
  • Clumsiness.
  • Loss of balance, particularly in the dark.
  • Dizziness, especially when getting up from a bed or a chair.
  • Sexual dysfunction.

It’s not easy to deal with neuropathy. If you notice symptoms, talk to your health care team immediately.

Factors that Increase the Risk of Neuropathy

Life factors that may increase the chances of developing neuropathy:

  • Advanced age.
  • A family history of neuropathy (such as with familial diabetes).
  • Malnourishment.
  • Excessive use of alcohol.
  • Having a preexisting medical condition such as diabetes or thyroid dysfunction.
  • Some medications (including chemotherapy medications) also increase risk.
  • What we find with our patients are that they will notice improvement within 3-4 weeks after starting treatment.

Medications that may increase the risk of neuropathy:

  • Platinum compounds.
  • Taxanes.
  • Vinca alkaloids.
  • Thalidomide.
  • Velcade.
  • Cytosine arabinoside.
  • Misonidazole.
  • Interferon.

Discuss all of these risks with your health care team.

Treatments for Neuropathy

The peripheral nerves have a great ability to heal. Even though it may take months, recovery can occur. However, in some situations, symptoms of neuropathy may lessen but not completely go away. For example, nerve injury caused by radiation often does not recover well. Neuropathy caused by chemotherapy is also difficult to cure, and recovery may take 18 months to five years or longer.

Recovery may be helped by:

  • Good nutrition including foods rich in thiamine, protein, and antioxidants.
  • Controlling and correcting contributing conditions such as diabetes or hypothyroidism.
  • Appropriate pain medications.
  • Physical and occupational therapy.

How Neuropathy Affects Your Life

Pain from neuropathy can greatly affect your daily activities and quality of life. Symptoms of neuropathy can range from mild to severe. Each survivor’s experience will be different. However, with appropriate treatment, the effects of neuropathy can be limited.

If you have neuropathy, you may have:

  • Difficulty standing for long periods or walking without assistance.
  • Problems with balance and an increased risk of falling.
  • Difficulty with activities like buttoning and tying laces or ties.
  • Sensitivity to heat or cold.
  • Numbness or lack of pain sensation.
  • Pain.

Survivors with temperature sensitivity should avoid extreme temperatures, and use protective clothing as needed. If there is numbness or an inability to feel pain, it is important to pay careful attention to the skin on the hands and feet because there could be an undetected wound or a break in the skin.
