Carpal tunnel syndrome occurs when the median nerve is compressed at the wrist, causing numbness, tingling or pain in the thumb, index and middle fingers—often worse at night. Care may start with night splinting and activity changes. Ultrasound-guided nerve hydrodissection may be considered in selected cases; persistent numbness or weakness needs prompt evaluation.
