Muscle spasm: 21 y.o. with unilateral popping sensation in region of shoulder blade likely has spasm of levator scapulae muscle w. intermittent impingement of taut tendon of this muscle by superior scapula spine, which is shaped like guitar pick; as scapula rotates in coronal plane during shoulder rotation.
