When I hold my breath I can feel something in my neck fill with air. Right under my ear. And it makes a weird sound when it does. I have to push on it to get the air out :s
Are you part squirrel or chipmunk lol idk that's weird for real
Its called your eustation (sp?) Tube. Its a tiny tube that fluid in your ears drains into your throat. Lots of kids get tubes in their ears when these tubes are not doing the job well enough. Nothing to worry about really. Unless there is pain.
