Generally finger numbness is a result of conditions that affect nerves and/or blood vessels that supply the fingers. It is also associated with tingling. It need to be sorted out if the problem associated with only left thumb. Frequent symptoms are referred as finger paresthesia.
Nerve issues are a common cause of numbness in the left thumb, or in the fingers. Nerves can also cause a tingling sensation in the fingers as well.

Numbness in the fingertips of the left hand can be caused by a variety of factors, including nerve compression (such as carpal tunnel syndrome), poor circulation, injury, or underlying medical conditions like diabetes or peripheral neuropathy. It is important to consult a healthcare professional for a proper diagnosis and treatment.
Pinched nerve in shoulder or c-spine
Sometimes leg numbness comes from standing or sitting for long periods of time without movement. This causes the blood to not circulate normally in the limb. Rotating the leg and foot can help with the circulation and relieve 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!:-)
Sharp pains in the left temple may need to be addressed by a doctor if they persist. Especially any pain that causes numbness in the face or neck should be checked out.
It can, the inflammation causes increase pressure on nerves, causing numbness in arm/fingertips
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.
