Peripheral neuropathy is a general term describing diseases of the peripheral nervous system. Peripheral nerves can get damaged from direct injury such as in cases of degenerative lumbar spine or autoimmune diseases affecting a component of peripehral nerves. Symptoms of tingling, burning, numbness and cramps can present in a symmetrical (in both limbs equally), or patchy (random) fashion. As the disease progresses, it can result in loss of balance or coordination. The prevalence of peripheral neuropathy in the general population is 2400 per 100,000 individuals, and this further increases to more than 8000 patients per 100,000 population in individuals over the age of 55.
