I did a fundus examination twice and it involves direct exposure to yellow light. I always get headaches and nausea and dizziness after the exam. I had a video meeting on teams and to increase brightness I used my little sister’s ring light. And 5 mins later I got headache and dizziness. Is it even possible that light could be a major trigger like that?
do you have a history of migraines? this is typical for migraine disorders
I don’t have a long history of migrane. It just came up all of a sudden 4 months ago. Trying to figure out what’s causing my illness, I found caffeine and bright light exposure and lack of sleep, which is one of the symptoms itself, are the biggest triggers. But the difference between me and typical migrane sufferers is that I’m suffering 24/7 not just 5 or 6 migranes a month and the rest of the month is fine I’m dealing with headaches and trampoline walking sensation and double vision and ringing in the ears among other symptoms 24/7. It waxes and waynes in terms of intensity but it never vanishes.
Have you seen a neurologist or otoneurologic physician? This sounds like migraine to me – I had all of these symptoms.
One of the common misconceptions regarding migraine is that there has to be distinct migraine events that are characterized by the classic migraine symptoms, but this isn’t always the case, especially with Chronic Migraine. With chronic migraine, one migraine even cycle often begins before the next one ends and you’re in a constant 24/7 loop of symptoms that never really seem to change. Nobody can diagnose here, but just based on my experience and reading about yours, its possible that you’re in a constant 24/7 loop of migraines that causes your chronic symptoms. The light sensitivity and caffeine triggers are really, really telling.
Highly highly recommend trying to talk to your GP or a neurologist about migraines/what their opinion is. Vestibular Migraine/complex migraine variants are difficult to treat, but they are highly treatable and most patients have favorable outcomes assuming that they’re compliant with what their doctor prescribes. Be hopeful 
edit: ENT/otoneurology are good to visit too. Just make sure you’re getting physician-directed care/workup for this

Inner or middle ear problems can cause this too. Mine’s always presented as an ear issue and mixed lighting can give me neurological symptoms. It’s all connected.
I suspect it is related to the strobing.
Either way, agree, go see an oto-neurologist. They can cover it whatever the underlying issue.

Yeah you need to be worked up…too many causes of dizziness that need to be ruled out. You’ll be fine though – sending you the best

I have been to 12 doctors so far. None gave me a diagnosis. Otoneurology is not available as a specialty in my country. We got ENTs, neurologists, and neurosurgeons. I’ll bring migrane up in my next visit to my neuro. Thanks!
Neurologists can dispense pills but can’t examine your ears.
In any case might be worth trying a med like Amitriptyline (like I did) or venlafaxine to see if it might improve symptoms.

I’ve found my current kryptonite … and it’s my local parks ice-cream van! 
For some reason if I buy an ice-cream and dare to dip my head into the vans side window to collect or pay I get momentarily dizzy.
I’m certain it’s the mix of natural light and the flashing strobe lighting in the van. It’s strange to have symptoms these days but this reaction is unmistakable.

I see several TV programs and Movies have warnings at the beginning about flashing lights causing adverse health reactions in some people. I always used to wonder who those people were. Now I are one of them!

I am very sensitive to light. My church revamped their lighting and I now need to wear sunglasses every Sunday at mass. If I have a headache, I wear a baseball cap as well. Friends thought I was trying to be fashionable! I need to have doctors lower their lighting in medical appointments. I find that visual field tests affect my gait so I bring a walker to help me walk out of appointments with a VFT (I have glaucoma) No problem with sounds. I am deaf.

I had forgotten that before my neurologist found the right drug combo, I had to wear sunglasses and a ball cap every time I went anywhere that had artificial lighting. I would also close the shades in their exam room. I remember once it was so bad I closed the shades and turned off the lights. I had a full blown migraine at the time. When the doc came in the room and found me in the dark with sunglasses on, he had a look of astonishment on his face. I think that was my last visit to him, I moved on to neurologist #3 after that.
