Does anyone have knowledge of or personal experience with visual migraines? Mine started in about 2005 and I'd have an episode about once every six months. Then in 2008 I had one and nothing since, until two days ago. I have no pain with them, but have experienced bad headaches (apparently caused by chiropractic problems in my neck from falls from horses back in the 1960s) much of my life. My opthalmologist seemed pretty unconcerned by this, but I wonder what, if anything, it all signals underneath the symptoms.
