I fell of the back of my moms car while in motion. I did not go to the doctor tho. It has been bout three months and i've had a constant headace it will get mild at times tho. I've also got sick and dizzy a lot I told a doctor about two weeks ago and he said it's hormons from being 14. My friends and family have told me I need an mri done but my doctor when I saw him said no need to. I don't know what to do.
