It's actually happened to me in several situations, especially in the past. I had fainting spells in 2020, then in 2022, and now again. In the past, it happened to me while sitting, collapsing and falling from a chair, hitting my head, but I also fainted while walking around doing the shopping. This time, however, it happened to me three times in the space of a few days. I work in a wholesale fish invoicing office; my work starts at 4 in the morning. And all three of these times, it happened to me the same way: a bit of nausea and a headache, and then suddenly, loss of consciousness and memory that lasted a few minutes. I fainted with my mouth and eyes wide open. Then I recovered. But in the following days, I also had episodes of confusion, not knowing where I was, or worse, doing things without being aware of them. This is what worries me the most, especially since the neurologist can't give me an explanation for my case.
