What causes thumb numbness?

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!:-)

What can cause numbness and tingling in left thumb?

There are many different possible causes to numbness or tingling. In this day and age the most likely is perhaps the slight pinching of nerves in the arm due to leaning on the edge of a desk. This happens frequently when playing games on the computer, or typing for a long time. Leaning on the left arm of a chair while watching TV can also pinch nerves in the arm or shoulder. Repetitive motion (carpal tunnel syndrome) from typing, thumbing a game controller, or even texting can contribute to tingling and numbness. Diabetes can also cause problems. So seriously consider seeing your doctor and get a blood test.
