I'm constantly dizzy, I get tunnel vision and light headed usually when I stand up. My eyes are always shaking back and forth. I get migraines everyday and the pain is usually directly behind my eyes. I've had my eyes checked out and I still have 20/20 vision. I'm 19 and last year I got shingles on my fact, my eye swelled up and i had blisters covering my left eye, forehead, and skull. When I touch a mark on my forehead that hasn't gone away it causes a sharp pain in my eye.
