I Flushed My Ears With Warm Water Today To Remove

I flushed my ears with warm water today to remove ear wax. I typically need the wax removed annually. I was feeling the buildup and since I am flying today (I am on the plane now) I felt I should remove the wax buildup before the flight. I was a bit dizzy while flushing but that subsided as soon as I stopped flushing. I am now on the plane and I feel moderately dizzy. I don't know why it returned. I wonder if it has something to do with the pressure on the plane. Any ideas? I am nervous to rent a car when I get to my destination.
