What clinical signs suggest carpal tunnel syndrome?

Carpal tunnel syndrome results from compression of the median nerve as it travels through the carpal tunnel. The key signs are sensory symptoms in the median nerve distribution of the hand—the thumb, index, middle fingers, and the radial half of the ring finger—often worse at night when the wrist is flexed, causing nocturnal paresthesias. Motor impact on the thenar muscles leads to weakness in the hand and may progress to noticeable thenar atrophy. Provocative tests like Phalen’s or Tinel’s can reproduce symptoms, further supporting median-nerve involvement. In contrast, numbness in the little finger points to ulnar nerve issues, numbness on the dorsum of the hand suggests radial nerve problems, and shoulder pain is not specific to this condition.
