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.
