Hi, for the past week i have been suffeing from pressure on the top of my head, which moves to the back of my head. I also just feel wierd and sometimes dizzy. My symptoms sem to change quite a lot and for the past few days i have been experiencing fullness in my ears. My vision is strange - althought i cant seem to describe my symptoms. I have been to the doctors twice and once i was given valium for anxiety as i told him sometimes i would get shaky and the second time i was told it was tension headaches and was given beta blockers. Please help as i am really scared and i am convinced that it is somethin serious!!
