I often experience visual disturbances that include spots, zig zags, colored
sprinkles, severe tunnel vision, severe loss of peripheral vision, blinding in one eye, blinding in both eyes for hours at a time this can go on for days at a time. The vision disturbances are worse the more severe the pain is. Some of my other daily symptoms can include: nausea, vomiting, dizziness, blackouts. I have anemia. I have a sleep disorder, so I rarely feel fully rested.
