[origamimaker]

A few days ago I slipped on ice twice and I can't extension or flexion but I can twist. I have never had this happen to me, I am only 17 going to college and this pain is killing me.  i have a tingling in my left leg, while my lower back hurt and when i try to move to much i get a sharp pain, also when going swimming i get a pain/tingling through my whole body.

This sounds like you may have pinched a nerve, or have some inflammation in your back. It could also be more serious, like a fractured vertebrae.

Since this pain follows an accident, and only things like x-rays or MRIs can determine for sure what's happened, you should really go to your student health center and get this checked, and skip the swimming and other exercise until you do.
