Research on the visual patterns that foreshadow migraines may reveal clues on how painful headaches arise from the brain even though it has no pain receptors.
Yes! I get started getting these a couple years back. Such a different sensation than a standard migraine. Like a march of color inversions across my field of view in little splotchies.
Thankfully, sleep is forever and always my go to treatment for it.
Tho, the first ocular migraine I had, I told my mom to call and check on me in a few hours to make sure I wasn't dead. Very scary the first time.
I occasionally get scintillating scotomas or whatever, like a stylized lightning bolt symbol had a cloaking device. Thankfully they've never led to headaches, just a weird vision thing sometimes
