I am two weeks post rhinoplasty and my left nostril is completely blocked by some swelling and red lump attached to septum. Air passage gets narrower everyday. However my right nostril functions very well. I am using antibiotic cream and isotonic spray but doesn't help much with left nostril. I had polyp removed from left side and deviated septum corrected. I have allergic rhinitis. What is happening to my left nostril? Is this situation normal?
