When the autonomic nerves, which manage involuntary body functions, are damaged, it causes neurological symptoms such as bladder dysfunction, hyperhidrosis, sexual dysfunction and anhidrosis. Damage to the motor nerves may cause twitches, paralysis and fatigue, states WebMD. These nerves control body movement. The sensory nerves send information from the skin and muscles to the brain for processing pain. Damage to the sensory nerves cause body pain, tingling and burning sensations, and sensitivity.

Peripheral neuropathy may be caused by trauma, vasculitis, kidney disease, infections and cancer, according to the National Institute of Neurological Disorders and Stroke. Other causes include toxins, neuromas and autoimmune diseases such as lupus and rheumatoid arthritis.
