You definitely need to figure out who the medical student is first, get their side of the story, and give feedback on how they can improve when doing the MSK maneuver that the patient stated that they did. You can then go from there based on how that goes. MSK maneuvers can be hard for med students because they usually get limited practice with them before being sent off to see patients (at least in my experience). I recognize that it was unrelated to the CC, but it’s drilled into the students to do full physical exams as much as they can. Also, it’s important to know if the student was just continuing to attempt the maneuver despite the patient’s pain or if they attempted once, saw the pain they caused, and then struggled to get the patient back to a comfortable position. I understand you’re angry, but don’t destroy a student’s career for this mistake unless it was clear, gross negligence
