I sneezed exceptionally hard or something recently and it feel like a "flap" came loose in the upper part of my nose. When i breathe in, the flap opens, and when i breathe out it closes. If you look up my nose when i blow out, you can see a flesh colored object cover up the air passage. It is so high up in my nose that you cannot even touch it or get to it with a finger or tweezers really. What the hell could this be? I am having a hard time sleeping and breathing
