Many people have numb fingers. The causes of such sensations may be different. In most cases, the fingers become numb as a result of circulatory disorders in the hands.

Apart from the above reasons, numbness in the fingers of the upper limbs can develop as a result of other systemic disorders. These include endocrine diseases, trauma, rheumatism, inflammation of the joints.
