I am way behind in updating my list of bookmarks myself. I only have one listed so far for season 10:

Property of Sam Winchester (http://archiveofourown.org/works/2649236?view_adult=true) by laurificus
Summary: Dean's got a mark on his arm, but Dean was Sam's first. (Wincest)

I don't remember if any of those three feature the shoulder injury directly, sorry. But this one does, if you don't mind RPF:Red (http://archiveofourown.org/works/2110941) by the megalosaurus is a great little season 10 fic about Jared's hurt shoulder (Jared/Jensen)
