For the past while (ever since I was a 13), I have been feeling a weird sensation in my eyes region at random times. I can't really explain it, but it feels like my eyes want to roll into the back of my head and I feel like I want to cry. If I let my eyes roll, it feels like I am stretching my eyes like if I was stretching my jaw (the feeling, not literally). This feeling is often accompanied by nausea and gagging even if I haven't eaten anything. The way I have been dealing with this is by taking a nap or going to bed. I am concerned that this can be something with my brain or nervous system more than my eyes. I have been to a psychologist and have been tested when I was a kid and I have nothing wrong with me. I have no previous history of epilepsy (I go to concerts and the flashing lights only bother my eyes when I stare for too long) Am I going insane?
