Sudden joint pain on knees
I was playing with legs bent when suddenly I started feeling a huge pain on my knees. After lots of screaming I managed to lower my legs, heared a "craaak" and then the pain eased. I already had several problems with pain there. It's not necessary to tell me to consult a doctor, I, of course, already did, and will do again. I just want to hear from you what this could be.
