What is peripheral neuropathy?
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.

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.
You may have physical therapy to increase muscle strength and help build muscle control. Over-the-counter medicine can relieve mild nerve pain. Your doctor may also prescribe medicine to help with severe pain, numbness, tingling, and weakness.
How can you care for yourself at home?
It's also a good idea to take care to avoid injury.
