Actress Jenna Fischer is finding filming the new season of U.S. TV hit The Office painful, five months after she fractured her back in four places. Fischer injured herself when she fell down a flight of stairs at New York club Buddakan in May (07) - and the 33-year-old is still struggling to lead a normal everyday life. She writes on her MySpace webpage: "I still can't wear clothes that are too tight because of my back. "Off set, I am literally living in sweatpants and pajamas. I think I am technically allowed to start working out a bit. But I'm going to pretend like I'm still only allowed to lounge around and watch TV while eating Ding Dongs. "I started going on light hikes recently and I suppose that is a good thing. Baby steps."
