Vertigo, unrelated to ear drum failure, is one you don't hear much about, but it happened to me, only once. Diving a Florida Spring, super clear water and deep. I was about 10 feet down and got an instant, very strong sense of vertigo, had no idea which way was up even though I could see it clearly. Only lasted a few seconds, but was EXTREMELY uncomfortable. The only extenuating circumstance I could think of was lack of a hood, but I'd been in for quite a while, so it shouldn't have had any effect.
