Headache from slipping on ice and hitting tailbone - should i be concerned? - when should you be concerned about a headache

I am now totally destroyed some ice and fell on my tailbone. My whole body feels good, but I had a headache over my head all day. I had no memory problem, so (it is not a concussion). Is this something I should worry?
