There's an old hurtSam fic that I would really like to read again, but can't remember the title or the author. It was pre-series, when Sam was a teenager. his leg was pinned by a pitchfork, I think, to a wall by a ghost. But the ghost was still there so there was no way to remove it without first ganking the ghost. Dean had gone to burn it, but meanwhile John had to keep Sam conscious and standing. I think maybe he sang to him? Anyway, i'd like to re-read the fic, so any help would be appreciated. Thanks!
Edit: found
