You are only 1 week from surgery. Swelling, asymmetry, numbness are all expected at this point of your healing process. I recommend you following up with your surgeon at your regular follow up appointments to discuss the healing process and address your concerns. The swelling will definitely come down. The final result should be judged only after you have had months of healing and sometimes up to 1 year.
At one week after a rhinoplasty all noses are extremely swollen, in particular in the tip area. There can also be asymmetries in the swelling that with time will settle and things will look symmetrical.
At this stage try not to analyse the nose too much. Wait for the swelling to go down over the next few months and stay in close contact with your surgeon so they can monitor your progress.
