I have been noticing recently that I sometimes get a spot in my vision very much like the ones you get after looking at a bright light. They are usually small and greenish/bluish. They are usually in one eye and fade after a few minutes. They are more visible when I squint and they dont' move around like floaters. I wouldn't be concerned except I get them when I know I haven't been looking at any bright light. I am terrified that I have a brain tumor or a detached retina. It's something most people might not notice but I am very focused on physical symptoms. I made an eye appt. for next month but I can't stop obsessing. I keep squinting to see if I can see one and if I think I do, I panic. Anyone else have this?
