Is Advil Advisable For Headache, Nausea And Body Ache?

Hi I slipped and fell on the ice, the back of my head I think literally bounced and I had to lay there for a minute until I could move. When I got up I had intense pain, then immediate blurred vision, headache, and nauseau. Of course the rest of my body had aches too, but has been a few hours since I fell and still have the nauseau and head ache...Can I take an advil? Or should |I continue to try and stay awake?
