It sounds like you have some unique physiology that make equalizing your ears difficult. Attempting a valsalva maneuver (pinching your nose closed and trying to exhale against it) with your chin tilted up and head leaned away from the offending ear can sometimes help. It straightens the eustachian tube out a bit.
While that’s not a bad idea, I’m content with the “fix” my doctor friend gave me. As for offending ear, it’s BOTH.
