[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.

Hi,
Usually when we fall, we tense up (brace ourselves) for the impact.  Usually muscle soreness relieves on it's own given a week or so. If the limited movement continues, or tingling worsens, a visit to your primary for evaluation would be my suggestion.
