I have experienced a tingling in my head behind my eyes. I am wondering if this may be a migraine. It usually happens when I am exposed to really loud noise for a while, or a long time spent in bright florescent lighting. Once it happened in college when I was cramming, I went to the hospital and they gave me a cat scan, said I was fine and gave me some atavan. Its not a pain but I am concerned. What are your thoughts?
