When the median nerve in the left arm is injured at the wrist and hand level, it can cause a range of symptoms that affect movement, sensation, and strength in the hand and fingers. This type of injury is commonly referred to as carpal tunnel syndrome.
The median nerve runs from the forearm to the hand and is responsible for providing sensation and movement to the thumb, index finger, middle finger, and half of the ring finger. When the nerve becomes compressed or damaged, it can cause pain, numbness, and weakness in these areas.
