What Causes Pain In Knee Caps?
hello, I twisted my knee a few days ago. I went for a walk and it started to crack - no pain. I went to sleep that night and in the morning my knee cap started to swell and I could not bend or straighten it fully. I can not put too much pressure on that leg either without pain. any idea of what i might have done to myself?
