I recently experienced severe knee pain after getting up from being on the floor with my legs tucked up under me. I knew the minute I got up that something when wrong in my left knee.
I have experienced pain in my knees in the past. Actually my first experience with knee pain was when I was 17 and at Drum Major Camp. I was going into my senior year of high school and had been selected senior drum major, a position I had tried out for in prior years but never landed.
