Finger numbness can cause tingling and a prickling feeling, as if someone were lightly touching your fingers with a needle. Sometimes the sensation can feel slightly burning. Finger numbness may affect your ability to pick things up.
Carpal tunnel syndrome is a condition in which there is excessive pressure on the median nerve. This is the nerve in the wrist that allows feeling and movement to parts of the hand. Carpal tunnel syndrome can lead to numbness, tingling, weakness, or muscle damage in the hand and fingers.
It is a depressingly modern condition in which the tendons around the thumb inflame as a result of repetitive strain — in my case because I had, for hours a day over years of a life, tapped that right-hand digit onto the glass of my smartphone. The condition sounds like the subject of a local television news trend story about teenagers whose thumbs seize up while they play video games. It was definitely not something I, a mature professional, should ever have.
It can be alarming to lose feeling in any part of your body. But losing feeling in one or both of your thumbs might seem especially odd. Thumbs help us hold cups, open bottles, and type on our smartphones.

Although carpal tunnel syndrome is a common condition associated with numb hands, it is not the only cause. Other potential causes are listed below. In addition to numbness, compression neuropathy can cause weak or twitchy muscles.
Numbness and tingling are common problems, and the nerve supply to the thumb and hand is complicated. If you feel a numbness in your thumb or hand, a nerve compression is a likely cause. While it is less common, it's important to know if the cause is something dangerous. However, the numbness is often associated with other symptoms in these cases.
Carpal tunnel syndrome is a condition that happens when the median nerve is compressed or squeezed as it passes through the wrist. This happens when the carpal tunnel inside your wrist becomes inflamed. The median nerve controls some of the muscles that move the thumb and carries information back to the brain about sensations in your thumb and fingers.
Carpal tunnel syndrome is a condition that causes numbness, tingling and other symptoms in the hand and arm. Carpal tunnel syndrome is caused by a compressed nerve in the carpal tunnel, a narrow passageway on the palm side of your wrist. The anatomy of your wrist, health problems and possibly repetitive hand motions can contribute to carpal tunnel syndrome.
