Got out of the bed and immediately my entire leg just collapses. I fall to the ground, and can't feel anything from Lower leg to my waist. I'm relatively okay now, but there is still pain a few hours later. It changes from a level of 3 to 7 or 8 on the pain rating. Did I sprain my knee? I kind of slumped to the ground and it bended backwards. I didn't hear a pop noise but I started holding my breath when I fell.

Going to the doctors tomorrow morning. But am curious as to what could have possibly happened. There was some slight tingling and pain just above my ankle and in my small toe before it happened.
