I started having eye problems about a year ago.  I noticed that bright lights (the flashing lights on top of towers, certain automobile tail lights, and digital alarm clocks) blinked as I moved my eyes if the objects and my eyes are both still, everything looks normal. It's very hard to explain.  If I roll my eyes while looking at my alarm clock, it looks like the clock is blinking like a strobe light, and it leaves a trail behind it like the clock is still in one spot when it is in another.  If I move my hand by my face, I see the trail there too. My hand seems to drag by. I went to eye doctor today and he found no pressure or anything else worng. He suggested I go to a neurologist and that I might be having occular migranes. What I'm seeing has been going on for 24 hrs a day for the last year.  Could this still be a migrane. I haven't had any headaches either. A little over a year ago I started noticing that when I lift something or strain my arms or legs a litte, they shake. I exercise regularly and started noticing this with even the slightest weight. My hair and eyelashes also started falling out very easily about this time. My main concern is brain tumor. I have an appointment with neurologist in a month, but am thinking the worst.
