My Daughter Is 10. She Has A History Of Headaches

My daughter is 10. She has a history of headaches and she is severely nearsighted (-5.00) in both eyes. These things developed after she hit her head on asphalt at the end of her kindergarten year. I can still see the place on her head where she hit it. Obviously it went down but it is still easy to see the exact spot where she hit. Should I be concerned about a deeper underlying problem?
