funny bone, highly sensitive area at the back of the elbow where the ulnar nerve passes close to the surface of the skin in a groove between end prominences of the humerus (the upper arm bone) and the ulna (the large forearm bone). A blow to the area causes the nerve to compress against bone, producing a characteristic tingling in the forearm and the last two fingers.

By bending their elbow too tightly, and for too long, they could overextend the ulnar nerve, which runs from the elbow to control our ring and little fingers, reports The Daily Express.
A special nerve called the ulnar nerve is wedged tightly between the bones and is also very close to the surface.
Repetitive strain disorders affecting these two fingers are usually either Guyon''s syndrome, entrapment of the ulnar nerve in the guyon''s canal at the wrist junction, or cubital tunnel syndrome, entrapment of the ulnar nerve at the elbow junction.
