Complications after a rhinoplasty are not very common. Swelling is not a complication. The worst swelling is gone after one week. Bruising around the eyes can occur if the nose bone is narrowed. This will fade within a few weeks. Infection is extremely rare because an antibiotic is administered during surgery. Nose bleeds may occur now and then. 

In some cases, there will be minor bleeding after removing the nasal tampons the morning after the procedure. This will stop within a few minutes. Severe bleeding is rare. Nasal congestion and discomfort when breathing through your nose are common in the first weeks. This is due to the swelling and wound scabs inside the nose. Rinsing with salt water will improve your ability to breathe. Most of the scars are made on the inside of the nose. After healing, the small scar on the ridge of the nose is almost invisible. The most significant risk is that the rhinoplasty result may not be what you expected. I try to avoid this by providing a good assessment, fair information and realistic prediction upfront.
