I just saw this thread. I whacked myself in the head one time with my car door lid. I went to step backward and close it at the same time and forgot the garage door was closed. Not enough room to step backward. I hit myself real hard. I saw stars, but did not go down. I got a concussion from that.

Maybe you should see your doctor about this pain. It may be nothing serious, but better to make sure. I understand your fear.
