Of course without an in person examination, one can never be certain but I would mention that most times that the nose is actually broken there is typically bleeding and severe swelling. In addition breathing can worsen if there have been changes on the inside of the nose. If you are truly concerned, please see a physician in person for an examination. Typically an X-ray is not required. Hope that helps!
There is no way to know if your nose is broken or bruised without an examination. Consult with a board certified plastic surgeon who is highly experienced to determine if any damage was done.
