Most people are probably familiar with carpal tunnel syndrome where impingement of the wrist (carpal tunnel) causes pain, tingling, and numbness primarily in the thumb, two adjacent fingers, and part of the palm. A similar condition can take place on the other side of the wrist where impingement of the ulnar nerve causes a radiating pain or numbness in the pinky finger, ring finger, and edge of the hand.
