Problems with my left ear

When I was in Junior Kindergarten, I put marbles in both my ears. I pulled them out several years later. I'm 31 years old now. Every now and then, I get this clogged sensation in my left ear that goes away very temporarily when I take a deep breathe. It comes back 5 seconds later. I can go many weeks with no problems, then all of a sudden I have a day where it's really bad. What should I do about this?

you should see an ent if you’re worried but it doesn’t sound like it’s anything serious.
