I have had horrible migraines and vision issues. The vision is still being figured out as to cause, but it gets blurry all of a sudden and sometimes the center is in focus but the edges are blurred. Sometimes after the blurry vision starts, I can't keep my eyes open. Some of my migraines are partial onset seizures, but I believe most are coming from my neck issues.

I had a headache for over a year before but it was bc I was having a shunt malfunction and it was 75 percent clogged. In getting it fixed I got double vision

Vision loss is generally my fist big symptom of a migraine for me. Like dolphinblues above mine are also linked to seizures.
