I am experiencing pressure in the top of my head. I was hit on top of my head about 10 years ago by a fouled baseball at a game, and I was wondering if maybe this is coming from that. I am used to Migraines, but now my headaches are different, they are more like constant pressure. I am also beginning to have blurred vission and trouble focusing. I have also noticed a change in my behaviors, I am easily "set off." I have noticed that I experience fits of rage at times. I have also noticed that I forget things easily and have no recollection of anything from more than about 10 years ago. I have noticed my symptoms getting worse. What could this be? I have recently started to get the feeling something is really wrong.
