What are the symptoms of a broken nose?

How can I tell if my nose is broken or if it's just smashed up and might not ever return to the way it used to look? I wiped out on my bike when I didn't see a speed bump. I had a helmet on but I face planted and my nose looks pretty beat up. I have not been in excruciating pain and I can still breathe but that doesn't necessarily mean it's not broken. I am still in some pain. What other symptoms should I be looking for? And how will I know if I'll need some kind of cosmetic surgery to make my nose look like it used to?
