I banged my head really hard on my car door arch. I bust open my eye brow. Had it glued together. It's been three days and my head hurts really bad.

See your doctor. If your entire head is hurting after 3 days have passed, Tylenol and hot compresses don't work.........It is time to go and see your family doc for an exam and some imaging! You can tell if something is terribly wrong. If instinct has led you to post this question, it is time to get professional help. The very best of wishes.
