about 4 years ago I got admitted to the mental health unit in Vinceness, IN.The reasons for that was because for weeks I thought I had a brain tumor. I thought I had most of the symptoms, and all I would do all day is read symptoms online, and ask medical questions on various forums. The main reason of me freaking out was because all of a sudden a feeling I've never experienced happened to me. I've never been able to properly explain it to anyone, but it seemed like something was blocking my realism, as if I were foggy headed, or I wasn't quite observant. Before getting admitted, I went through the ER. There they gave me a CT Scan, and everything came back normal. The ER doctor said I simply had sinus problems. The next week while at the hospital, they had run several blood tests as well as a MRI which my psychiatrist had me get because my pupils were uneven. And again, the MRI test came back normal. But a symptom I had then, and still do have today (a symptom I even had 2 years before my brain tumor freakout), is an eye problem, but is neurological related. All this time I thought it was double vision, but doing some research, I found someone with the same issue who even posted an example image, and this is what I experience daily: http://i.epvpimg.com/YyyAg.jpg
Also if I put out my hand, and make an arc with my hand, there is a trail behind it. Even if I'm looking at a small light for example, I'll look left and right (always keeping the light in my center vision) and I'll see a streak of the light through my vision. So still today those 2 eye symptoms I have, I don't have any idea what those could be caused from. I'm wondering if it could be caused from my anxiety, or some sort of mental disorder. Hopefully this gives you some insight on what's causing this issue.
