Oh my gosh. I wonder if it could be orthostatic hypotension. That is when your blood pressure suddenly drops - it usually happens after suddenly standing up from sitting. But, you could also have a blood pressure drop in the shower due to warm/hot water - as it causes your blood vessels to dilate and then your blood pressure drops. Your heart rate then increases, trying to get your pressure up. You can black out/faint and everything. Does it sound like that at all?
In any case, my thoughts are with you - and I hope all turns out well.
