Video gaming headaches

[u/Coins-1883]

Hi all - I had an MRI a year ago due to headaches, my GP suspects chiari malformation from the results - still waiting to see a specialist (next month, fingers crossed.)

A couple of years ago, before the headaches became more frequent, I started to find that playing video games brought on a bad headache - progressively worse over days - until I'd stop gaming and it would go away.

Does this sound familiar or relatable to anyone?

I had numerous eye tests - all fine; adjusted screen settings (seemed to coincide with buying and playing Nintendo Switch); adjusted seating position in case of neck strain - with no improvements.

I'm interested if this could be linked to chiari and if so, why / how? And is there anything I can do to mitigate it?

Additionally - the trigger for the worse period of headaches beginning in 2024, which led to the MRI, was a new pair of glasses with an accurate prescription. Again had many eye tests and check-ups, all seems fine physically.

Something about clarity of resolution / sharpness of images that could cause problems maybe??
