What causes tingling in the hands and feet?

ANSWER

Diabetes is one of the most common causes of peripheral neuropathy, accounting for about 30% of cases. In people with diabetic neuropathy, tingling and other symptoms often first develop in both feet and go up the legs, followed by tingling and other symptoms that affect both hands and go up the arms. About two-thirds of people with diabetes have mild to severe forms of nerve damage. In many cases, these symptoms are the first signs of diabetes.

In another 30% of peripheral neuropathy cases, the cause is unknown, or "idiopathic."
