Go to your doctor, tell him/her that your neck hurts so bad you can't turn your head (maybe stop at Walgreen's first and buy a neck brace). Also, your back is in such terrible pain you cannot sleep at night or go to school at work. Get her to write this all down for you and give you the appropriate scripts, then..
go find yourself a good (read shyster) lawyer who works on commission and sue the bastard that did this to you!!!
Rmember, neither x-rays nor MRIs can prove or disprove back pain, play it right and you're stinkin rich
