I Fell While Rollerskating At A Roller Rink And Landed

I fell while rollerskating at a roller rink and landed super hard on my tailbone on Sunday 12/14/14. Instantly my head hurt, I would have bet money that my head hit the floor, but it did not, unfortunately this fall is on video. The next day, today, Monday 12/15/14 I have a severe headache, I feel like I pulled every muscle on the left side of my neck, my abdominal muscle feel like I I've did 1 to many crunches, the muscle that runs along the shoulder blade hurts and to top it off I've had to have surgery twice this past year for a level 1 fusion at L4-L5. I'm not having spinal pain but I can not sit on my buttock. I'm also 39. Is this normal for a hard tailbone hit at my age. I'm concerned about the spine but a little more concerned about the headache and neck pain. Please advice. Thank you.
