Hi I'm 178cm, 75kg, male. I don't have any previous medical history.
I have a strange question. When I pressurize my sinuses by covering my nose and pressing air into my head(the way you do while diving under water), I hear a squeaky sound for as long as I continue, and afterwards I might loose my balance, but It's followed by a sense of sharpened eye sight. It also gets easier to breath through my nose for a couple of hours. What worries me is if it's dangerous, or if I should get my nose bone fixed. So I can breath easily through my nose permanently. This problem started a few years ago after a fight and I got hit on my nose.
