There are a few different types of hand-tingling: tingling that occurs in both hands, tingling that occurs in one hand and tingling that occurs in the fingers. Tingling that occurs in one hand or specific fingers is usually caused by a problem with that hand or finger, while tingling in both hands or all fingers is usually caused by an underlying condition within the body.

Alcohol abuse, multiple sclerosis and vitamin B13 deficiency also cause nerve damage and can lead to tingling in both hands. Additionally, tingling in both hands can be a sign of heart disease and can occur during a heart attack. Carpal tunnel syndrome is a nerve problem that often affects both hands.
Tingling in One Hand
A tingling feeling in one hand can be a symptom of a stroke, which is a serious medical condition that requires immediate action. Other less worrisome causes for tingling in one hand include nerve damage that is the result of a hand injury or tingling that is the result of an infected cut.
Tingling in the Fingers
Tingling in a specific finger will usually be caused by an injury to that finger that has resulted in nerve damage or infection. Frostbite is another common cause of tingling in fingers.
