Bruises
When your collarbone is broken, surrounding blood vessels can also be damaged. As a result, it can make a blood leak in the affected area. This leads to a buildup of fluids in the tissues, which can be visible as bruising. At first, bruises tend to start with a blue or purple color, then gradually turn yellow or green when the body reabsorbs the blood. In some cases, you can find bruises far from the affected site of the break because the blood can be moved through the body. [3]
