Can diabetes cause nerve damage?

What are the symptoms of nerve damage caused by diabetes?

Nerve damage usually affects the toes and feet first. Some people do not feel any symptoms, but other people can have symptoms that include:
  • Numbness or loss of feeling
  • Burning or pain – Pain is often worse at rest or at night.
  • Tingling
  • Feeling light touches as bothersome or painful
  • As nerve damage gets worse, symptoms can move from the feet up the legs. Once people feel symptoms in the middle of their lower legs, they might also start to feel symptoms in their hands.

    Is there a test for nerve damage caused by diabetes?

    Yes. Your doctor can usually tell if you have nerve damage by talking with you and doing an exam. Sometimes, a doctor will do a test to check how well a person’s nerves are working. This test is called “electromyography.”
