Tingling in the pinky finger can be caused by a disorder of the neck spine, anatomical abnormality around the clavicle (cervical rib, anomalous muscles resulting in thoracic outlet syndrome), disorders of the elbow (cubital tunnel syndrome), wrist (Guyon's canal syndrome), hand (hammer hand syndrome) or the pinky finger itself (injury).
Numbness in the hand and ring and pinkie fingers is known as cubital tunnel syndrome. It occurs because the ulnar nerve is subject to a variety of problems, including friction, ulnar nerve dislocation, and impingement of the ulnar nerve, and all of these problems can cause numbness in these fingers.he most common cause cause for numbness and tingling in the hand is carpal tunnel syndrome which is compression of the median nerve in the carpal tunnel of the wrist. This can be painful at the wrist and will typically will cause numbness in the thumb, index and middle finger.
