What causes sinus swelling?

I often wake up in the morning with what seems to be swelling on one side or the other in my sinuses. I can breath through one nostril but the other is closed almost completely. There is no indication of any boogers blocking it and eventually it will open back up. Sometimes the swelling may shift from one side to the other over time but I don’t know why. Looking for tips on identifying the cause and prevention. Thanks!
