There are several possible explanations as to why these visible injuries are still there. Either Lovegood hasn't returned to headquarters yet, or Granger made the conscious decision not to go to the trauma room. I could even understand the latter, since in recent years I, too, have often forced myself to let my non-fatal wounds heal naturally. As a reminder of how much I deserve to suffer. Well, maybe we don't differ that much from each other when it comes to our masochism.
