Anything is possible, as well as necrosis. The doctors are doing the right thing by following up. As for now, there is not much you can do, except try to enjoy your holidays, and deal with the results as they come in, which is easy to say, and been there many times myself. Keeping busy helps. With the holidays there is no shortage of that, plenty of movies, specials in TV, foods, events, friends and family visiting, celebration.
Good luck.
