For the books I am no doctor and can not make any dr. decisions. IMHO, I think it was a sinus related block. Maybe when you started you had a clear sinus and so on, but maybe it became cloged or irratated as to playing with your mask not fitting. I have had exactly what you speak of but felt the sinus pressure immediatly in the pool. So I knew something was going to happen sooner or later. Depending on your equalization method, you could of streched something in your ear that caused the dizzy effect. Once that repairs itself and goes back to normal I would think you would be fine with the dizzy part. But your sinus problem may be still lurking. It is allergy season!! Bunch of over the counter drugs you can get your hands on to clear your sinus issues (if that was the problem in the first place). I think if you feel the sinus pressure gone and the "knot" gone, go for it. I must say after the first time you run into this, you become very much more aware (sensitive) of the new pressure and can tell early if something is not right.
Remember it's your body and no matter what anyone tells you, you are the only one that can feel the pain. What I mean is, you decide if you are ready and no one else. So be very in tune with your sinuses and treat them well. There is always another day ahead of the rest.
Take care, get better, and happy diving!!!!
