I have cramping in my right elbow only when driving and my hand goes numb in the last two fingers. The numbing goes away the cramping usually lasts?

Possible nerve issue. Numbness to two fingers and cramping associated with certain positions could be a nerve impingement issue. This should be checked by your doctor to confirm a diagnosis and develop a possible treatment plan.
Ulnar neuritis. Your history is suggestive of ulnar neuritis. The ulnar nerve may be stretched or compressed in certain positions, causing characteristic numbness in the 4th & 5th fingers. At the elbow, excessive/prolonged flexion (bending), may cause this. At the wrist, compression at the ulnar (same side as pinkie finger) base of the palm can irritate the nerve. Do your best to avoid these positions.
