I was diving in Turks and Caicos just over a month ago when I was suddenly hit by a very bad dizzy spell. We were only down at about 65'. It was a night dive, and I ended up signaling my buddy to help me get back to the boat because I was having a hard time telling up from down let alone where the boat was. About 2 minutes later the dizziness was gone and I felt fine. I ended my dive anyway because I wasn't sure what had happened or whether it would be back.
The next day I had the same thing happen, but I realized it occurred after about a 3' ascent, so I dropped back down and the dizziness was gone.
I did 25 dives that week and only had the two incidences, but I'm interested if this is unique and of opinions as to what could cause this. Could this be due to a reverse block (I don't recall any ear pain before during or after), and if so any suggestion as to how to prevent it? The first episode was bad enough that my dive buddy said my eyes were rolling around my eye sockets like ping pong balls. He thought at first that I was blacking out, but I was responding to his signals and giving signals back ok. My mental capacity was fine, just my head was spinning so fast I was completely lost.
