The sad thing is I already have a herniated disk in my lower back. Also I'm already going to physical therapy. I definatly know I have a neck injury but it seems to be just slight stiffness of the neck. I've been streching and tiger balming it for the last three days and it seems to have gotten better. I think what saved me is might hight (6'5"). The head rest in my car comes up to about where my spine conects to my skull so when i got nailed it stopped my head from flying back. But I need to go to my doctor anyway for checkup for my back.
