I've done the same thing my bro Solax over there does, and guess what, it works.
Anyway, when I go swimming sometime, and then I go deep down into the dark waters of the pool, my ears always pop. I go deaf for like 10 minutes. First time I experienced that, I was like, oh no, I'm deaf forever. XD But anyway, if the popping starts to hurt a bit, don't hesitate to see a doctor. ;)
