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

Abnormal smells following rhinoplasty surgery may be caused
by a variety of problems. When these smells are encountered three weeks after
surgery they should be aggressively investigated. It’s therefore important to
see your surgeon as soon as possible.The
smell that you describe could be related to a large number of potential
problems. These may include nasal or sinus infections, wound healing problems,
necrotic tissue, crusting with retained mucous secretions and retained nasal
packing.In the
majority of cases nasal cleansing with saline irrigation will solve the
problem. In some cases antibiotics may be helpful as well.

This is normal but you should check with your doctor to make sure there are no infections or foreign objects (packing) left behind. Irritations with saline usually helps.  If you would like a second opinion, feel free to call my office to schedule a consultation.  - Dr Azizzadeh
