- Diseases of arteries like atherosclerosis, Buerger’s disease, and pulmonary hypertension.
- Carpal tunnel syndrome, in which the median nerve is compressed causing numbness and pain in the hand, even making the hand more susceptible to cold.
- The repetitive action of the wrist such as playing the piano or any action that requires repetitive action can cause nerve injury causing numbness and tingling sensation in hands.
