This is a question that I answered for someone who wondered about the above. You should always sleep upright the first 48 hours after your rhinoplasty (or Nose Job / Nose Plastic Surgery / rhinoplasty / Nose cosmetic surgery). If you can tolerate it, sleeping upright will help your swelling go down even more after the first 48 hours. This allows gravity to help your swelling. Icing is also helpfiul. Sleeping with your head in the middle and not turned to one side or the other also keeps things symmetrical. To avoid swelling a course of steroids can help. Also avoiding blowing your nose and drinking hot or spicy liquids. Avoiding how showers and anything hot is a good idea as well. The time that you can get oozing and swelling is greatest the first 48 hours and then the first 7 days. After the first 7 days oozing goes down quite a bit. I hope this answers your question.
