The more uncomfortable feeling that most patients experience is a feeling of congestion and stuffiness for a couple of weeks. This feeling gets worse over the first few days following surgery, but by the end of the first week the swelling is coming down and most patients begin to feel significantly better. It takes about two weeks for the patient to become "sociable." What that means is that, by two weeks, much of the swelling and bruising has resolved and patients are feeling close to normal again. There is still swelling at that point, but strangers won't notice this when you are out in public.
It takes six weeks for the bones to heal completely back together again, so exercise and vigorous activity should be limited during that time. By three months, the swelling is resolving more and the nose will look very similar to the final product. Having said that, it does take about one year for all of the swelling to resolve and for the nose to completely heal. It may take longer than this in cases of revision rhinoplasty.
There is also a psychological component of healing that takes place following rhinoplasty, as your brain must integrate your new look into your self-image -- this usually takes a couple of months. With support from family and your surgeon, you should be able to navigate the healing process successfully.
