It takes time to recover from invasive surgeries. For a nose job, it might take one year or two for your nose to take its final form. The time of healing is different for different patients and different noses. Ask your doctor to give you a rough estimate of the recovery time and be prepared to take his/her advice during that time. If you think that you might be in difficult circumstances after your surgery, such as having to perform a demanding job or being under heavy physical pressure, think twice about going for a nose job until you find a time after which you would be more comfortable and less busy.
Also, keep in mind that every surgery (plastic or not) has some (often short-term) side effects. You will have some swelling following a Rhinoplasty which usually lasts for one month. Your face might become puffy immediately after the surgery and you might have black eyes. All these side effects will go away within a few weeks.
You should be ready to restrict your head movement or your sleep position for a few days after your Rhinoplasty. Therefore, it is highly recommended that you receive enough information about the dos and don’ts for nose surgery recovery period either by consulting your doctor or browsing reliable websites, prior to the procedure.
