Some causes of finger paresthesia arise from nerve compression (pressure or entrapment) or damage. Finger paresthesia can be due to any activity that causes prolonged pressure on a nerve or nerves, such as fine motor activities (drawing), repetitive motion (keyboarding), and sleeping the wrong way on your arm.
