Serious shoulder pain can be caused by a rotator cuff injury or damage in the joint socket. In either case, it is best to see a doctor and avoid physical activity such as dip exercises until getting medical clearance. In less serious cases, such as general soreness or pain from muscle weakness, dip exercises can add the strength and flexibility needed to build up the shoulder and eliminate future discomfort. You can do easier dip exercises at the onset of shoulder pain and increase the degree of difficulty as the pain eases and you gain strength.
