Carpal tunnel syndrome is a condition caused by repetitive motions like repeated wrist movements or typing.

Such movements can result in pressure on the nerve that goes through the arm’s length. The nerve is known as the meridian nerve. Once the nerve reaches the wrist, it moves through a narrow passage known as the carpal tunnel.

The nerve controls the movement of the first three fingers and the thumb. A different nerve controls the movement of the pinky finger.

People with this condition experience itching or numbness in the finger and thumb. This feeling is often accompanied by trouble holding objects and hand weakness.

As the condition worsens, people experience muscle pain and cramping. They may also begin to lose grip strength. This is because of the improper function of the median nerve. Orthopedic hand specialists treat this condition before it becomes worse.
