My Nose Has an Odor Like A Bad Smell Inside, I Had Rhino 3weeks Ago

It is important that you consult your plastic surgeon as soon as possible. A strange odor secreting from the site of surgery is not entirely uncommon, and is usually the result of either sweating from bandaging or extraneous mucous concentrated in the area. On rare occasions, the scent may be an indication of infection. Your situation must be evaluated in person in order to more accurately determine the root of the smell and ensure that the healing process is going according to plan.

While this is not unheard of it is usually uncommon and can mean several things.  The key is an EXAM by your surgeon to look inside and see what is going on. It is usually from xs dried mucous or tissue that is not alive and must removed.  An infection can also occur but it is quite uncommon.  Using saline nasal spray may help but most often your surgeon needs to clean out your nose in the officeDr Rahban

Usually, this is caused by there being old blood or crusts inside the nose that bacteria thrive on.  In these instances, clearing the crust will make the problem go away.  Saline nasal spray will slowly wash away the crust without the trauma of nose blowing.  If you are not having increasing pain, redness, swelling, fevers or drainage, its unlikely to be infection.  Either way, keep your surgeon in the look especially if the smell doesn't go away after a few days of the saline nasal spray.  It may be that he will need to look in your nose to see what the issue is.
