Peripheral neuropathy is a disease that can damage nerves in the feet and prevent them from working properly. It is commonly caused by diabetes or injury.
Some causes include arthritis, vitamin deficiencies (which is why we test), blood vessel disease, and certain infections. Damaged nerves may cause changes in sensation, including numbness. This can make you more likely to injure your feet without knowing it.
Over time, neuropathy can lead to permanent loss of nerve function, as well as bone and joint damage.
