Neuropathy

Neuropathy
Neuropathy translates as nerve damage. People who have been unaware for several years that they have diabetes, or who have had uncontrolled high blood sugar for a long period of time may develop nerve damage. Prolonged high blood sugar causes damage to several parts of the nervous system. Sensation may become abnormal and tingling or burning pain may develop. Damage to the nerves of the skin makes damage more likely because the person can’t feel changes in pressure or temperature.
