Numbness in the fingers can be described as the hand falling asleep, or a pins and needles sensation in one or more fingers. Besides a tingling sensation, the individual may find it difficult to grasp or pick up objects. Finger numbness can be due to minor ailments or more serious conditions.
Carpal tunnel syndrome is a common condition, especially in those who perform repetitive motions with their wrists and hands. Usually, carpal tunnel occurs in the median nerve, which runs from the neck to the hand. This crucial nerve provides feeling to the palm side of the hand and fingers. When it becomes irritated or inflamed, the carpal tunnel narrows and presses on the median nerve, resulting in numbness in the thumb, index, middle, and ring fingers. Risk factors for developing carpal tunnel syndrome include anatomic factors such as bone and nerve structure, obesity, nerve-damaging conditions, and inflammatory conditions, in addition to repetitive tasks such as typing.
