Re: Flashing light in both eyes.
I have Migraine Associated Vertigo and I have "aura's". Mine are wavy lines in my vision that are followed by what I call "sparkles" (in my vision where everything I see is sparkeling) and then I get a headache about 15 minutes after that.
My headaches are not the killer migraines but seemingly just normal headaches.. The name "Migraine Associated Vertigo" is very misleading. I have had vertigo in the past but I no longer have that instead I just have balance issues and sometimes get a different kind of dizzy than vertigo. There are a varity of symptoms you can have with MAV and never have a headache.
My eye doctor was the first to mention migraines to me when I complained of those aura's and asked me if I got a headache afterwards. I didn't associate the aura's with the headaches until she said that, but I do get them afterwards. Other symptoms I have, nausea, motion sickness (from just walking), sensitivity to lights, especially florescent lighting, dizziness and I stumble and stagger a lot because of the balance issues.
DO get your eyes checked and if they check out ok, then you need to see a neurologist.
Until then, I suggest you look up MAV on the internet and see if it fits what is happening to you..
