outdoorzgirl: I know what you mean, i really do, i also have the aura/vertigo/visual disturbance, many names for it, Ive had everyday it for a year now and its just awful isnt it :-(.
I suffer from chronic daily migraine with visual disturbance, i get the visual thing everyday and migrianes constantly, and i also cant go in shops because of the lighting, i cant work or drive due to my head pain and vision. Its so disortintating isnt it? I dont know if your the same but i cant go for a walk or anything on my own as i feel so dizzy. The computter is sooooooooooo bad for my eyes, but silly me sits here on this site. I struggle reading etc. I too wear sun glasses as much as possible when im out. I also struggle to travel in a car as it makes me feel so disorintated.
I dont know what meds you have tried, but the only tablets that helped ease my vision was verapamil, it didnt get rid of it, but it helped.
Good luck to you.
