Common symptoms of a fractured collarbone include:
Pain, swelling and tenderness along your collarbone
Pain when you try to move your shoulder or arm
Slumping of your shoulder downward, forward and inward
Abnormal contour of your collarbone — The fractured area may cause an abnormal bump along the length of your collarbone, or it may poke forward to produce a sharp point under the skin at the front of your shoulder. In rare cases, the end of the broken collarbone may penetrate through the surface skin and be exposed.
Bruising or abrasions along your collarbone, or at the top or side of your shoulder
