Mine are called migraine with aura as I see wavy lines or gold rings around my whole eyeballs. Two times all of my vision went bright white and once gray. I feel the prodrome coming on when I get a sharp intense smell or the lines or rings. Depending on how fast it comes on and how strong the pain, means I’ll be in a dark room in bed for days.
When I was younger I took the cheaper Excedrin equivalent, which is caffeine from a coke/coffee/or chocolate, an aspirin and an acetaminophen. Prescription meds made me too dizzy so I was put on gabapentin and vimpat for seizures. They mostly work for migraines but sometimes I have to add a tylenol or a coke and it usually works as I’m already on aspirin for my cholesterol.
None of my doctors over 60 years have known what causes them but I have a lot of other diagnoses so I figure it’s related to my seizures even though they don’t think so. I also have small vessel disease and a lot of migraine scarring in my brain but all my neuros say it’s no big deal. They don’t have migraines lol
