"I am afraid that you are in no condition to leave. In fact you are fortunate to be alive. If we hadn't been able to stop your internal bleeding when we did you would be dead by now; we don't have any compatible blood for a transfusion. You also appear to have pneumonia, or at least your species' version of it, which will require medication. We think you may have a concussion as well, which will require monitoring to ensure that it does not result in permanent brain damage. This is not counting multiple fractured ribs, severe lacerations and incisions that required stitches, as well as frostbite. As it stands now you will need to stay here for several weeks at minimum, followed by minimal exertion for several more weeks once you leave."
