I recently took a spill down about 3 steps, i mainly hit on my rear and my side. It happened so fast I m not exactly sure, but that was where most of my pain was. Since then I have had a headache daily and at times it feels as though I m being hit in the back of the head, just about the neck area, with a brick. I m definitely making a dr. appointment, but i wonder if I should maybe go to the ER?
