Is it normal that i get a weird crunching noise in my ear

Go to the dr if you don't think you have stuck a few marbles in your ear.

See a ENT or your physician! There could be something stuck in there!

omg that sound is always in my ear. not sure what it is but i have gotten used to it and sometimes i think its fun to make it happen. i like my friends to listen to my ears pop too they think its cool/weird

I have TMJ and my jaw "clicks" and makes all sorts of sounds when I move my jaw. Sometimes it's just allergies. Stop eating/drinking dairy to keep the fluids thin and drink more water.

I usually get that with congestion. Try stretching your jaw, like a big yawn, and massage around your ears while you do. It should help your ears to drain, and help put the everything back in place.

I had that once, it lasted a few days and went. If it doesn't go soon I'd go and see the dr!

Go to the doctor, there's probably something stuck in there. I remember reading about a kid who had the same problem, and when he went to the doctor, they found two spiders (one dead, one still alive) inside his ear.

Does it happen when you swallow too?

It's normal. Stop clenching your teeth and flexing the muscles in your jaw before you develop an actual problem. Fucking shit.
