About 4 weeks ago I started having weird visual trailing. By this I mean at times, not all the time, when I see something for example my hand in front of my face as it moves I see like trails or like the outline of the hand where it had been like it’s lagging behind like a shadow. It’s both eyes and only really when I’m tired. No pain just weird trailing. Saw dr who was unsure, sent me to specsavers, they said nothing on the scans, so now I’m having a head CT this week. I’m really worried. Anyone else have this?
