I've had palinopsia "vision trails" off and on for 9 years now. Some years are good, some are bad. They always seem to come when summer turns to early fall, as did the first bout which caused me to have anxiety. My arms hurt, my legs hurt, and I have a pain (unlike a headache pain) in the back of my head. Has anyone else experienced this?

No, I have never taken LSD, heroin, or anything else...although I did have a DR prescribe me "ellavill" an anti-depressant which I did not need. 

Do you have pains in the back of your head that come with your palinopsia? (Result)

Yes

No
