Yeah, that's happened to me a couple of times, fortunately I've never had to have the problem professionally dealt with.

As for personal revelations though, recently I seem to have one really hard and crumbly bit stuck right close to the eardrum. I can't get it out with q-tips because it starts hurting and I hear a crackling sound. So I just left it in... I know it's earwax because I got some of it on the q-tip before it started hurting and I got the q-tip the hell out of there.
