This may sound weird, but clean your ears out...and not with Q tips which push the wax in. I had an older student that couldn't equalize at all and had sore ears after a pool session. He went in to see the doc and he had a big wax build up which prevented him from equalizing. Had his ears cleaned out and returned to complete his course a couple of weeks later.
There's drops available at the drugstore that you flush out with water afterwards. I do this a week before our big cave trips and haven't had issues since (although I still use ear beer during the trip).
