Superficial contusion if you got medical help and no complications is just dead skin cells from swelling secondary to contusion

Please see a medical doctor.

To explain what happened: I stumbled getting off a city bus and fell face-first onto the sidewalk, hitting my nose in the process. A couple of kind passersby tended to me and called 911. At the hospital, they did a couple of cat scans (the second one was because of blood in my urine, they told me.) They put me in bed in the emergency room, until they got the results of the cat scans back.

They told me I had a fracture. The doctor and I talked about it for a few minutes, and he said I could go home that evening. He said that it might heal on its own, but that I should see an ear, nose and throat doctor. He gave me a couple of referrals. I will see an ENT doctor Monday morning.

My nose looks pretty straight to me. My breathing seems normal, and I'm able to blow my nose normally now. It just has this sort of rash or scab on my nose. I am hopeful that no surgery will be needed.

Another commenter, a doctor, said that he thought it was a bruise beneath the skin, and that it should clear up soon on its own. Anyway, I had never experienced or seen anything like this before, and I was curious.

Um yeah, some things are beyond the level of expertise of the internet commentator.

You really should get this attended to. Not going to nag but it sounds like you might have a septal haemotoma. What on earth did you do? Please go to your GP

I was thinking broken blood vessel until I read the part where it's flaking. Now I'm not sure. I broke my nose about 10 years ago, but I don't remember anything like that.

How did you break it? Is it crooked or deviated? Did one or both sides bleed? Any problem breathing, especially through one side?
