(HealthDay News) - Diabetics are prone to many complications, particularly if their blood sugar levels aren't well controlled.

Diabetic neuropathy, or nerve damage, makes it difficult for the nerves to send signals to other parts of the body. The symptoms described below should be evaluated by a physician without delay.

The American Academy of Family Physicians lists these warning signs of nerve damage in diabetics:

  • Numbness, particularly in the fingers or toes.
  • Sharp pains or a tingling sensation.
  • Sores found on the feet.
  • Weakness in the muscles.
  • A burning sensation anywhere in the body.
  • Male erectile dysfunction.
