Symptoms of nerve damage of the feet include pain with a sharp or burning sensation, numbness and tingling, sensitivity when touched, and a lack of coordination, states Mayo Clinic. Nerve damage of the feet is known as perpheral neuropathy, a condition in which sensory, motor or autonomic functions are impaired.
Diabetes and high blood sugar are the leading causes of nerve damage of the feet, notes MedlinePlus. Other health conditions that may trigger nerve damage include kidney or liver disease, thyroid disorders, and inadequate blood flow to the limbs. Low levels of vitamins, specifically vitamin B-12, and poisoning from heavy metals, such as lead, may also contribute to the onset of peripheral neuropathy.
