I think it's because you're going a bit too far and touching a nerve thatwas primarily involved in swallowing food (I said food but you can go with @creativedragonbaby interpretation too).
In fact it's not really good to use Q-tips, you should use ear spray or a thing that looks like a hybrid between a toothpick and a spoon that enables you to scoop up the earwax instead of pushing it in your ear canal.
Or just get an ear infection and have the doctor either syringe it out or go to a specialist to have it vaccumed out, proceeding to get swimmers ear in the process in the first case
Yes! I did that and the doctor pumped water in my ears, it felt like I was falling even though I was laying down and then like had been spinning for 20 minutes, I wasn't walking straight and someone handed me a pamphlet for my alochol problem.
