Multiple questions about migraines and temporary blindness.?

My response is confined to #1 and 2. Yes a migraine can cause temporary inability to see. I don't know if i would give a diagnosis of blindness. I think one protective measure you can take is to wear sungles year round. A buddy who happens to a neurologist explained to me most migraines are related to excess sunlight entering the brain via the eyes. It is possible that a migraine has a more serious cause that would warrant a neurological workup. I think those who think a migraine is just another headache should experience just one. I vomited during the early years when I had my onset of migraines. But, back to you: you should undergo testing of the brain and then your neurologist can make a treatment plan for your complaints. This needs to be attacked sooner than later.
