Hi -
A few weeks ago, I was sitting at my desk at work. No real stress, pretty calm. All of a sudden, my vision started to disappear from the top left corner diagonally down. It was like a shadow was walking into my peripheral vision, or a curtain was coming down, just bizzarre, so I turned to see what it was. There was nothing there and my vision came back. It didn't last but maybe 5 seconds, but it was definitely weird. My blood pressure is usually fine, but sometimes spikes up to 180/90 for short periods (an hour or so, maybe), usually when I'm stressed. My cardiologist mentioned that those spikes weren't good and could lead to a stroke. My question is, since this episode was so brief, could it have been a TIA?
Thanks.
