Peripheral neuropathy results from damage to the peripheral nervous system, which sends information between the brain and spinal cord and the rest of the body. Sufferers may experience numbness, pricking sensations, weakness or hypersensitivity. The result may be paralysis, organ and gland dysfunction, muscle wasting, and problems with digestion, sweating, sexual function and urination. At worst, there may be breathing problems or organ failure. Symptoms may occur suddenly or can be experienced over years.
