Shoulder sprain, broken collarbone and weightlifter’s shoulder are some conditions that cause collarbone pain. According to Drugs.com, a painful collarbone can indicate a torn ligament, also referred to as a shoulder sprain. Torn ligaments of the shoulders typically occur at the acromioclavicular joint, which is the joint that connects the acromin and the collarbone. Shoulder sprains can also occur at the joint between the collarbone and the breastbone, commonly referred to as the sternoclavicular joint.

The American Academy of Orthopedic Surgeons explains that a broken collarbone is a common injury that is caused by a direct hit to the shoulder. Symptoms include a shoulder that sags down and forward, bruising and tenderness above the collarbone, a bump located above the break and limited mobility of the arm. Treatment ranges from arm slings or wraps to surgery, depending on the severity of the injury.

According to Houston Methodist Orthopedics and Sports Medicine, a condition referred to as weightlifter’s shoulder can cause aching in the front of the shoulder at the acromioclavicular joint. Pressing on the joint can cause weakness and additional pain. This condition can also cause pain when moving the arm across the body. Weightlifter’s shoulder is typically associated with degenerative bone issues in body builders, and the pain often becomes worse with weight training. Treatment consists of physical therapy and a change in the body builder’s weight training routine or surgery to remove the end of the clavicle.
