A buddy of mine did so much blow in the 80's his nose tissue dissolved and he had to hit the body shop for a rebuild. After he got fixed he couldn't believe the smells he had all but forgotten.
That's a pre op pic cause your sinuses would be packed with gauze, and the worst pain ever in my life was the 3 weeks after surgery where they pulled the packing out. While it opened up a world of smells, worst pain.
