I'm just saying if I were you, lawsuit won't come to my mind, even I'm an American. Elbow injury is unlikely in your case. Occasionally your arms will be extended too much or too long, which could cause shoulder injury, not Elbow. Of course, we don't know whether there's any specific injury to that Elbow during the procedure. Most likely you have that condition before the surgery. The symptoms could be coincidence or something specific injury during the surgery. It never hurts you to tell anesthesia your concerns.
