I've been advised by many medical professionals not to put Q tips in ears, with can push wax in there into places where it won't come out without medical intervention (I had to get my ears syringed because of it).

The sensation you are talking about is caused by the Eustachian tube being blocked or partially blocked, doing the manuevre to equalise pressure is done by blowing out while holding your nose and mouth closed, this equalizes the pressure between your ears and the outside environment, hopefully getting rid of any discomfort, (the manuevre is quite uncomfortable in itself unfortunately.)
