I've never broken my nose before, nor been at the scene of such an accident. So my questions are these:
What are the immediate and long-term effects of a broken nose caused by a sharp blow to the face? Can a person set a broken nose himself, or must he have professional help? (My character is a medic; if such a thing is possible, he'd know how to do so; what would he do?) Most importantly, what would the results be for his (superpowered) sense of smell? Would he be able to smell anything, just to smell blood, or not to smell anything at all?
Thanks for your help!
