First off I'm a hypochondriac. I just wanted to put that out there but don't belittle my worry because of it. I've had two concussions before I think and suffered from PCS during the first one. My worry lately has been an aneurysm because of these odd headaches and dizziness and blurry vision. But i just remembered I had hit my head last week. Not that hard. I just rubbed on the area and moved on. It was the top back right of my head I think. I was getting into the back of my work van and hit my head on the metal frame. As I said not hard. Well now I'm wondering if I have a concussion/hematoma or something. I also have a slight temperature of 99.1
