About three days ago while moving furniture, I hit myself pretty hard in the nose. I was momentarily stunned but did not become unconscious, nor was I dizzy after the first stun wore off (just a few seconds). My first thought was that I broke my nose because it hurt quite badly, but after feeling up and down the nose, I don't think it's broken--no blood, no swelling, no movement. So I just went about my business. Next day, I had a feeling of congestion in my ears, like a head cold. I vaguely wondered if it could be related to getting hit in the head, but on the other hand it's the season for head colds. Now the feeling of congestion has mostly but not completely gone away. On the one hand, it's good that it's reduced. On the other hand, it makes it seem like not a head cold. Could I have done some damage to myself? Is there anything that can be done about it if I did?
