A nerve problem that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. It usually begins in the hands or feet and gets worse over time. Neuropathy may be caused by cancer or cancer treatment, such as chemotherapy. It may also be caused by physical injury, infection, toxic substances, or conditions such as diabetes, kidney failure, or malnutrition. Also called peripheral neuropathy.

The most common symptoms of peripheral neuropathy include burning, numbness, tingling, or shooting or stabbing pain in the toes and/or fingertips. If you have peripheral neuropathy, it is important to inspect your feet regularly. Because decreased sensation may develop eventually, you might not notice an injury or infection.

A healthy diet, increased physical activity, and well-controlled blood sugars, along with regular visits to your podiatrist, may help to avoid complications of diabetes such as peripheral neuropathy.
