hard to explain but not blurry or double vision --

I posted about being in a car how I felt awful for 2 days...(I think that was one of the causes)

I don't watch tv (rarely) my head feels all shook up...walking, talking, reading etc. even going on the computer a few mins

I've had my eyes checked and I was wearing prism lenses but they didnt' seem to be doing anything so I stopped. I don't see any difference with or without them on. Should I go back to my optomotrist? How do I describe this??
