In January I was in a car accident where I was in the back seat when a girl slammed into the back of our stopped car. I know I hit my head because I was holding it when my sister turned around to check on me. There were no bumps or anything, and I didn t get it checked out when I went to the hospital. My neck hurt for a couple weeks after the accident. Since then I ve been getting headaches and dizzy spells quite frequently. Is this normal to be happening this long after the accident or would something else be causing these symptoms?
