What symptom typically correlates with CTS that worsens at night?

• A. Loss of dexterity
• B. Shoulder pain
• C. Elbow stiffness
• D. Knee swelling

Answer: (A)

Carpal tunnel syndrome (CTS) is characterized by compression of the median nerve as it passes through the wrist, leading to a range of symptoms. One of the hallmark features of CTS is the presence of nocturnal symptoms, which often include tingling, numbness, or pain in the fingers. These symptoms tend to worsen at night, frequently disrupting sleep.

Loss of dexterity is a significant symptom of CTS as well. As the condition progresses, individuals may find it increasingly difficult to perform fine motor tasks that require hand coordination, such as buttoning a shirt or typing. The deterioration of hand function is directly linked to the increased discomfort and neurological symptoms experienced during the night.

In contrast, the other options—shoulder pain, elbow stiffness, and knee swelling—do not specifically correlate with carpal tunnel syndrome. Shoulder pain might be related to conditions affecting the shoulder girdle or cervical spine, elbow stiffness could be indicative of local issues within the elbow joint or surrounding tissues, and knee swelling typically pertains to lower limb pathology, none of which are characteristic of CTS.
