Peripheral neuropathy is a condition in which nerve damage in the feet or hands leads to weakness, tingling, and numbness. When the peripheral nerves can’t relay signals to the brain, this can cause pain, usually a pins-and-needles or burning feeling, leading to a partial or total loss of sensation. Other related issues may also arise. You may not notice an injury such as a break in the skin on your foot until infection has set in. Or you may begin having issues with balance and suffer a bad fall. Peripheral neuropathy is more than just damaged nerves and it can affect your sleep and your lifestyle.
