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.
