Suddenly Felt Light Headed, Dizzy, Pain In Head, Neck, Back And Abdomen. What To Do?

Question : Hello. I was driving to work about 9 hours ago, during good weather with no isses. I felt lightheaded and dizzy and I closed my eyes for just a second, the next thing I knew I was facing the sky. My car had run full speed at a diagonal and my car ran up the large ditch. The shock and noise of the accident broke my fuzzy feeling and then I began to panic once the car settled. I hurried and got out of the car for fear of fire. I did wear my seat belt, however, the airbags didn't deploy. Upon leaving the scene, I felt fine, just shaken up. I'm sure I didn't have anything serious, but my all-over soreness is unnerving and painful. The pain is in my head, neck, back, lower right abdomen. What would you recommend I do next? I was able to work a full shift tonight, but my pain is increasing. My head, neck, back, lower right abdomen are all the most sore. I'm not bleeding, vomiting, or anything so I don't feel its necessary that I go to the ED. Are there any signs to look out for that should send me to the ED?
