Carpal tunnel syndrome (CTS) is the most common nerve compression syndrome—so much so that, according to the National Center for Health Statistics, at least 1.89 million people suffer from the condition.

CTS occurs when the median nerve in the wrist’s narrow carpal tunnel becomes compressed by surrounding soft tissue. This compression reduces blood flow to the nerve and contributes to symptoms that include burning, tingling and numbness in the thumb and index and middle fingers. Pain in the forearm is also a common complaint.
