What causes the pitching arm to ache at the shoulder or elbow?
Too much STRESS on the shoulder and/or elbow. Bending the elbow, before snapping the wrist, is usually the cause of elbow pain. The pitcher will get elbow snap instead of Wrist Snap. Having the throwing -side elbow too far from the body or the shoulder up too high is usually the cause of shoulder problems. Both of these will cause too much STRESS in the joints. A more common reason is over-use. Even with an elastic arm, there can be some aching in the arm.
