Numbness and tingling that spread upward into the legs; sharp, jabbing or burning pain; sensitivity to touch; lack of coordination; and falling are symptoms of peripheral neuropathy of the feet, notes Mayo Clinic. People who have peripheral neuropathy of the feet may also experience muscle weakness or paralysis if motor nerves are affected.
People suffer from mononeuropathy when one nerve in their feet is affected, multiple neuropathy when two or more nerves in one area are affected, and polyneuropathy when many nerves are affected, states Mayo Clinic. Poor diet, diabetes, certain medications, infections, and trauma or pressure on the nerves of the feet can cause neuropathy. Diabetics who do not control their sugar levels, people with autoimmune diseases, people with a family history of the condition, and people with kidney, liver or thyroid disorders are at greater risk of suffering from neuropathy.
People who have foot neuropathy are at greater risk of burns and skin trauma because their feet are numb and not sensitive to temperature changes or pain, notes Mayo Clinic. Infections are another complication related to foot neuropathy, as people may be unaware of injuries and fail to treat them properly. Doctors diagnose neuropathy by collecting full medical histories from patients, conducting neurological exams and using tests such as computerized tomography, magnetic resonance imaging and nerve function tests.
