I have suffered with chronic Migraines for the last 7 years. I have beeen on every drug cocktail that you think of with no succuss. My nero. told me on my last visit that they have exhausted all medical treatments. And as you, I suffer from blurred vision and now My family has noticed that I have one eye that drups. When The blurred vision fisrt started I went to my eye doctor,but no problem! Depending on how severe my headache is that day depends whether if I have Blurred vision in 1 eye or both but since I have daily headaches the vision problem does progress during as the day goes on so of course evening's are worse. I also have started having problems with my balance which I don't know if it's connected to the vision or not.
I have heard of other suffers with simialiar issues, in my case I'm going to seek out a new specialist so I can have my life back!
