The top of my head has a non-painful pressure in one spot and it just makes me feel sickish and not normal. It has been going on since last Saturday 24/7. My eyes can only focus on one thing and are jumpy at some times. I have been tired for the last 3 days most of the day. I have looked at other sites and think it is from axiety, depression, or a brain tumor. I was grabbing a boat anchor and the bar on top swung down and hit me in the head. It could be from that. I don't know if it's concussion or what?
