It may result from damage to the nerves supplying the thumb or from damage to or occlusion of the blood supply somewhere higher up the arm. Severe damage to the thumb itself may also cause considerable loss of sensitivity. Theoretically, at least, it might also be caused by damage to the opposite side of the brain, but in such cases, the numbness will probably affect a wide range of regions of the arm and shoulder.
In a dumb bum, too much rum could also cause a numb thumb--among other things!:-)
