What causes numbness in thumb index and middle finger?

This includes the palm, thumb, index finger, middle finger, and thumb side of the ring finger. The area in your wrist where the nerve enters the hand is called the carpal tunnel. This tunnel is normally narrow. Any swelling can pinch the nerve and cause pain, numbness, tingling or weakness.

Regarding this, what does it mean when you have numbness in your fingers?

Numbness of the fingers and/or hands typically is a result of conditions that affect the nerves and/or blood vessels that supply the hand. These symptoms are referred to as paresthesia of the fingers. Peripheral neuropathy is damage to the nerves of the extremities that often results in numbness or tingling.

Why do fingers go numb for no reason?

Causes. Hand numbness is usually caused by damage, irritation or compression of one of the nerves or a branch of one of the nerves in your arm and wrist. Diseases affecting the peripheral nerves, such as diabetes, also can cause numbness, although with diabetes similar symptoms usually occur first in your feet.

Why does the tip of my finger go numb?

Numbness is typically a sign that a nerve has been pinched or damaged. The most common cause of numbness in the part of the hand that you describe (the ring finger) would be carpal tunnel syndrome, which is a condition in which the median nerve, which runs down the center of the wrist, becomes pinched or inflamed.
