Had my nose broken when I was 18 playing aussie rules football.
I was sprinting, full pace, for about 20 yards, towards the ball which was on the ground.
Guy from the other team, doing exactly the same, from the other side.
I slid down onto my knees, skidded on my knees and grabbed the ball - he ran straight into me and kneed me, running at full pace, square in the face.
Mashed my nose across my face - not like C shaped, more like \ if you know what I mean (if | is straight nose, \ was how mine looked).
I held onto the ball and passed it off - kept playing for a few minutes before I realised anything was wrong - didnt hurt too much, I only realised something was up when I went to jump - couldnt really balance properly - had minor concussion, I guess.
Anyways, went to the hospital (hehe - I walked off to the boundary and asked a mate of mine ‘hey rob, does my nose look broken?’ - ‘nah Finny it’s fine mate’, walked up to my mother and asked her - she just grabbed her bag and goes ‘lets go [to hospital]’)
At the hospital, the newbie doctor, must’ve been 25 or so, gets a cresent shaped needle of anasthetic, inserts the needle between my eyebrows, and runs it under the skin, down the side of my nose - pulls it out and does the same on the other side.
Once the anasthetic took affect, he clamps down on my head with his arms, and starts to SHOVE my nose back into place - it didn’t just pop back in, as I expected, he had to really wrestle it (almost crushed my head - I could feel some serious pressure on my temple where he was holding my head in place).
Regardless, to answer your questions - my nose was seriously broken, and didnt bleed - I’ve never really been susceptible to nose bleeds.
Only other injury to describe what’s going on could be swelling from the blow - but from the way you described it, sounds like a broken nose to me.
You can have a broken nose without producing serious or sharp pain - dull ache was about how I’d describe mine.
Scale of 1-10, I’d say 3 for me. If that - it really wasnt that bad.
The thing with a broken nose - the only problem he’s gonna have is if it alters the way his nose looked previously.
If he doesnt think it looks bad/different (after the swelling recedes), then just leave it - doctors won’t do anything about it unless it’s disfigured - and even then they will likely only do what they did to me, just to try to get it back in place. If he wants it properly fixed, gotta see a plastic surgeon - screw that.
Keep us posted.
