Does your face look ugly after surgery?

My mother had overie removal surgery a couple of weeks ago and every day that passes she can walk and is recovering physically but her face is getting worse and worse in my opinion. Her nose is swelling very badly, she has spots on her face and just looks abnormally old, right before the surgery she was great and then after the surgery her face just suddenly dropped. When her overie ruptured she was in great pain so they continuously gave her a lot of pain killers and a lot of other kinds of medicine I think, could it be because of that, her face is just abnormally bad and has gotten worse everyday since the surgery in my opinion. Is this a procedure that she needs to pass, because of the large dose of medicine or etc what's causing this.
