In between the bones there are layers of cartilages cushioning the bones. The shoulder has two main joints. The glenohumeral joint is made up of the humerus bone and the edge of the scapula. The acromioclavicular joint is between the scapula and clavicle. The movement of the shoulders can be circular, backwards and forewards. There are many causes of shoulder pain.
