Since it's swollen, you might have torn something...tell your mom that it's FAR too painful to be a "strain"...there's lots of liganments, lots of tendons, and cartiledge in a knee. Lots of things to get injured. You screw up a knee when you're young, you will be paying for it later. Tell her that.

To be on the safe side, you may want to consult a doctor.
Phrannie's right!
