I fell and hit my head twice in the last yr. No I didn't go to hospital but I'm having a lot of pain on both sides of my head. The first time I knocked out over three hrs and it busted my head open that had my hair caked with blood. I'd how long I was out for the last time. My question is should I still be hurting. The reason I fell was because my back locked up on me. Should I still be experiencing this pain for this length of time?
