I was playing Futsal 4hours ago, someone tackled me, I couldn't help my self but hit the ground with my left cheek. I didn't have any headache or difficulty in laughing, remembering my name, date , the place or talking and walking. I still don't have any of those problems.
I came home, took a shower. Now I see there is blood in my mucus.
Is it a concussion? I didn't have any symptoms of it ( I read a lot & I know about it) . Or it's just my nose, bleeding?
