You can’t have any results after 3 weekend post operation! The rhinoplasty is the most slow in term as of recovery! It takes at list 2/3 months to start seeing the results, and up to 1 year to be 100% recovered. Trust me, I had a nose job done in the past.
You need to have patience and take care of your nose to have a proper recovery! Also, you can not blame the surgeon, because the results are not visible for you in 3 weeks post operation, that is simply impossible! Some patients are swelled for 4 weeks after the surgery, therefore, you can’t expect to be fully recovered in 3 weekes !
