Here’s my experience with them:
Thanks for bringing this up. I get the same damn things, one of my brothers used to get headache-inducing migraines, and another used to get abdominal migraines (just bad nausea about once a month), my mom gets headache-inducing migraines along with abdominal migraines, and my grandmother gets ocular migraines. My visual disturbances are associated with a very mild dizziness, but no weakness in either leg, no pain, and no nausea.
For the record, I’m a man. No gender is spared.
Oh, and mine look like a piece cut out of my visual field and replaced with black static. The pieces are usually round, often half-moon shapes that ‘bracket’ the center of vision on one side or the other.
I have optical migraines and mine begin as a field of random flashes in the center of my field of vision that gradually expands into a field of ‘black static’ (think old-fashioned analog TV static, but black instead of white) with the flashes on the periphery. This changes shape to bracket the center of my field of vision on one side or the other (usually the right side, I think), and grows outwards like a shock wave with constant width but increasing radius until it’s grown all the way out of my visual field. This is associated with, at most, extremely mild pain at some undefinable location in my head.
I suppose I should also say that the visual disturbance and the dizziness make it difficult to read or write while the migraine is ongoing, but I can walk around just fine.
Do any other ocular migraine sufferers have a family history of migraines of any type?
