Carpal tunnel syndrome (CTS) is a common medical condition that affects the hand and wrist. It occurs when the median nerve, which runs from the forearm into the hand, becomes compressed or squeezed at the wrist. The carpal tunnel is a narrow passageway in the wrist formed by bones and ligaments, and it houses the median nerve along with tendons that control finger movement.

The compression of the median nerve can result in a variety of symptoms, including:

● Numbness or tingling in the thumb, index, middle, and ring fingers.

● Pain or a burning sensation in the hand or wrist, which can sometimes radiate up the arm.

● Weakness in the hand, making it difficult to grasp or hold objects.

Carpal tunnel syndrome is often associated with repetitive hand and wrist movements, which can lead to inflammation and swelling within the carpal tunnel. This condition is more common in individuals who perform activities that involve repetitive motions, such as typing on a keyboard, using vibrating hand tools, or engaging in activities that require forceful gripping. It is also more common in women and can be linked to conditions like pregnancy, diabetes, and arthritis.
