Hit front of head yesterday on corner of bathroom sink. it hurts in that spot and i have a really bad headache mostly in back of my head. suggestions?

My first question: would be "how on earth did you hit four head on the corner of the bathroom sink?" Did you pass out ? Bend over to inspect the contents of the commode ? Have a seizure ? Apparently there was enough force involved as to cause a whiplash injury (or someone clubbed you from behind). If you don't get better in a few hours or if you don't know how you hit your head see a doctor ! Makes sense?
