I was kneeling, lost my balance, fell back onto my feet with my butt, and heard three loud pops in my knee (I "over-bent" my knee.... I immediately stetched my leg out to try and reduce the pain, it did not go away. Now I have a bump about the size of cherry at the base of my quad/right above my knee. Now I have pain in my calf, my knee hurts, and there is a bruide around the area. I can walk, and stand on it, but my knee does not feel stable (feels like i bends backwards more than normal).
