What is not a symptom of carpal tunnel syndrome?

Numbness in the little finger is not a symptom of carpal tunnel syndrome because this condition primarily affects the median nerve, which does not supply sensation to the little finger. Instead, the median nerve innervates the thumb, index finger, middle finger, and part of the ring finger. Therefore, symptoms of carpal tunnel syndrome typically include numbness or tingling in these specific fingers, as well as pain in the wrist.

The other choices involve symptoms that are classically associated with carpal tunnel syndrome. Pain in the wrist can occur due to compression of the median nerve as it passes through the carpal tunnel. Likewise, tingling or numbness in the thumb and index finger is indicative of the condition and can be early signs that someone is experiencing median nerve compression.
