Crackling Noise
Another common symptom of a broken collarbone is the grinding or cracking sound when you move your arm. This noise is caused when the broken parts come in physical contact with each other. Depending on the angle, severity, and force, the bone might fracture or crack in two or many clean pieces. The sound you hear can be actually the noise of the bone groups or bone that received the unexpected damage and impact. Since this sign is very simple to notice, make sure to contact your healthcare provider immediately to prevent worsened problems. If left untreated, a broken collarbone can become serious and affect surrounding tissues and muscles. [6]
