Hi I m Sierra and I got hit in the head a year ago and now I rehit my head on the floor and there s a shooting pain towards the left of my forehead even though I got hit on the right side. I can t remember much, not even from a week ago. I Have trouble focusing. Appetite is fine and sleep is normal I m very tired but this is not related. I have a messed up head with many injuries and my friends are worried that I have a concussion or depression. While I m here, I also have knee problems. I might have sprained my acl. It bothers me when I turn. I also crave pain killers and have taken Advil every six hours for a very long time. Will I die from taking all of these painkillers and could they cause any of my issues and what is wrong with my head?
