Feeling weak, dizzy, and shaky from bright lights

Hey there!
Total newbie here, so please bear with me if I mess anything up!
I couldn't find a thread for this anywhere, so I actually just signed up specifically to ask this—even though I’ve been lurking and reading your posts for ages.
So, basically, whenever I'm under these super bright lights (not just regular house lights, but like those intense ones you see in big retailers like Target or Walmart), I start feeling really weak. My vision gets all blurry, I get this lightheadedness—kind of like dizziness—and my body starts shaking, almost like my blood sugar is crashing or my blood pressure is dropping.
I've been falling down internet rabbit holes trying to figure it out, and the only thing I keep seeing is stuff about anxiety, but honestly, I’ve never dealt with anxiety in my life. It’s just this weird weakness that hits me out of nowhere. I'm not freaking out or anything, but man, it feels pretty lousy.
Does anyone have any clue what might be causing this, or who I should actually go see?
Just for context, I've always been pretty healthy. I'm 27, average build, nothing crazy going on.

Look, just go get an EEG. Get a solid opinion from your primary care doctor first, then head in for the actual test after you've pulled a total all-nighter to make sure they catch everything.

Thanks for getting back to me!
So I went and told my GP what’s been going on, and honestly? Her big takeaway was just that "plenty of people deal with this," and... yeah, that was basically it. Total nothingburger. 🤷
Are you thinking epilepsy or something? Just wondering since you mentioned the EEG.

There are several neurological issues you need to rule out. You have to push your doctor for a specialist referral! Telling you that "lots of people have this problem" isn't a medical diagnosis—it's a brush-off. Sure, plenty of people suffer from all sorts of conditions, but they actually get diagnosed, just like plenty of people undergo tests only to be told everything is "fine" when it clearly isn't. Don't let them cut corners on your care just to save some insurance paperwork!

Well, I find myself grappling with that very same issue, though in my case, it’s been compounded by layers of anxiety, which has left its own lingering traces... regardless, it isn't something I take lightly. I did undergo a neurological consultation, but it was merely a standard checkup; the doctor seemed convinced that further investigation was unnecessary, attributing the root cause entirely to my anxiety levels.
I have heard whispers that quite a few people experience this, whether they struggle with anxiety or not—it often stems from those unnatural light sources, especially if they are improperly installed and prone to flickering...
Though, I suppose I am still left wondering whether I ought to insist upon at least an EEG.🤷
