what are the diseases that causes peripheral neuropathy?

Answer 1

Excerpted from WebMD: "Many things can cause peripheral neuropathies so it is often difficult to discern the cause. In fact, in up to one in three cases, the cause cannot be determined. Diabetes is responsible for another third. Other known causes include several rare inherited diseases, alcoholism, toxins and certain environmental agents, poor nutrition or vitamin deficiency, trauma due to compression, herniated discs in the back, certain kinds of cancer, conditions where nerves are mistakenly attacked by the body's own immune system or damaged by an overaggressive response to injury, particular medications, kidney disease, thyroid disease, and infections such as Lyme disease, shingles or AIDS."
