Of his volition, he didn't use any medication. Toward probably the last week. I think he used something like Tylenol or Excedrin, over-the-counter medication. There wasn't anything too much that interrupted how he was doing. Probably the last twelve hours, at that point he was moaning and in a lot of pain. And it was strongly suggested we use a pain killer. At that point he wasn't consciously responding. I don't know if we did the right thing or not. We did, in the last twelve hours, use one injection of a pain killer.
