Neuropathy, also referred to as neuralgia or neuritis, is a type of pain that involves the nerves. Neuropathy results from nerve degeneration, pressure, inflammation, or infection. There are several causes of neuropathy, including carpal tunnel syndrome, pinched nerves, spinal stenosis, and pressure from spinal discs.he sensory nerves send signals about what you feel, such as heat, cold, pain, and touch.
