Last year an object fell from the ceiling hitting the front top of my head and both eyes. I blacked out for about a minute. I received a cut on my left eyebrow, lose of memory, headaches, slurred speech, agitation, headaches, sensitivity to loud noises, when I walked or drove in the car my head would spin, and I had raccoon eyes. Dr diagnosed me with post concussion syndrome. It s been a year and I m still have memory loss, when I get tired slurred speech, headaches, loud noises cause my head to hurt and the black eyes come back. What would be causing these symptoms?
