I've injured the tendon or ligament where the throat and collarbone attach. I heard it "pop" ! My neck is moveable but "puffy"

I rolled onto my sholder during a Martial Arts demo. The pain and "pop" made me think at first I fractured my clavical. My neck is moveable without pain, but I can feel discomfort at the neck near my throat when I raise my arm and putting on my shirt. Is this TENDON or LIGAMENTS? My own treatment has been ICE & ADVIL.
