Below, you’ll learn about 15 possible causes of this sensation and get guidance on when to seek medical help.

Tingling in the hands is most often caused by restricted blood flow to the area. This can happen when you fall asleep on your limbs in an uncomfortable position or if you sit on your hands for long periods of time.

1. Diabetic neuropathy

This is a type of nerve damage that affects people with diabetes. Diabetic neuropathy can affect both the hands and feet of people with diabetes.

It usually starts with a tingling sensation in the fingertips, which can extend down the arms. People with diabetes have higher blood sugar levels, which damages the nerves and limits the supply of oxygen through the bloodstream.

Other symptoms of diabetic neuropathy include frequent urination or uncontrollable bladder, numbness in the limbs, muscle weakness, and sharp, throbbing pains throughout the body.
