Particularly during the first twenty-four hours-your face will feel puffy, your nose may ache, and you may have a dull headache. You can control any discomfort with the pain medication prescribed by your surgeon. Plan on staying in bed with your head elevated (except for going to the bathroom) for the first day.
You'll notice that the swelling and bruising around your eyes will increase at first, reaching a peak after two or three days. Applying cold compresses will reduce this swelling and make you feel a bit better. In any case, you'll feel a lot better than you look. Most of the swelling and bruising should disappear within two weeks or so. (Some subtle swelling-unnoticeable to anyone but you and your surgeon-will remain for several months.)
