Peripheral neuropathy is a problem that affects the peripheral nerves. These are the nerves that control your sense of touch, how you feel pain and temperature, and your muscle strength. Most of the time the problem starts in the fingers and toes. As it gets worse, it moves into the limbs, causing pain and loss of feeling in the feet, legs, and hands.
When you have peripheral neuropathy, you may have less feeling in your fingers and toes. You may have trouble with your balance. It may be hard to do things that require coordination, such as walking or fastening buttons.
It can be hard to diagnose peripheral neuropathy, because symptoms can vary. People who have diabetes need to get a complete foot exam every year. During the foot exam, the doctor will check for signs of this peripheral neuropathy.
Your doctor will start by asking questions about:
Your medical history, including use of alcohol, risk of HIV infection, or exposure to toxic substances.
Your family's medical history, including nerve disease.
Your doctor may also test your muscle strength and ability to feel touch, temperature, and pain. These tests include electromyography and nerve conduction tests.
You may also have blood tests to find out if you have diabetes, vitamin deficiencies, thyroid disease, or kidney problems that might cause neuropathy.
How is it treated?
The focus of treatment for peripheral neuropathy is to relieve symptoms by treating the health problem that's causing it. For example, vitamin deficiency caused by overuse of alcohol can be treated by eating a healthy diet, taking vitamin supplements, and stopping alcohol use. If you have diabetes, controlling your blood sugar can slow neuropathy and may improve it.
