Finger numbness can be caused by many things, from pinched nerves to diabetes. Finger numbness can also be a sign of more severe conditions, such as stroke.
Finger numbness is a partial or total loss of sensation in your fingers. It’s relatively common. For example, your hand may “fall asleep” because you put pressure on a nerve without realizing it. This feeling will usually go away once you change positions.
That said, finger numbness that doesn’t go away or gradually worsens may be a sign of an underlying health condition that could require medical treatment.
