I hit my head like a week and a half ago on the refrigerator freezer door. I picked up ice to put it in the freezer, and when I came back up the door was closing so I went straight into the door on top of my head. Since then I feel like I've been a little confused with my speech, and at work I forget little things that I'm normally good at. I feel dizzy majority of the time, and light headed all the time. Off and on throughout the day I get headaches as well. And tonight I accidentally got hit on the head by someone sleeping pretty hard as they we're bringing their arms down. Do I have anything to worry about?
