I've been having near fainting spells, on and off, the past several months. Bloodwork ruled out anything of a physical nature. My primary, didn't want to rule out my MS, but fainting or near fainting with dizzy spells isn't an MS symptom.
My pdoc, wasn't quite certain what it could be. Just wants me to monitor, what it is that happens when these occur. Though, I am on a take as needed script for Xanax, and since I've been on it, I haven't had these moments, he wasn't ruling anxiety in nor out.
I had eaten, many times over, prior to these spells, but, my pdoc, did mention that dehydration can be a factor. As can side effects from sleeping pills the night before. Which, these moments, didn't happen the last time I had one, the night before.

You mention, not eating. And I am left wondering, if maybe, I hadn't had enough water going into these near fainting spells??

Dehydration? As a cause for fainting? What are your thoughts, looking back on your own fainting spells?



PS, sorry to hear about the concussion!! Are you feeling, OK, now??
