my knees suck

Jiu jitsu. My knee said "pop!" I said "what?" And it didn't reply. I guess that's a good thing. I had my other knee pop about two weeks ago. Two weeks of inconvenience but it feels fine now. I am thinking worse case scenario it's just another ligament tear. Maybe not even that. I'll see how it feels tomorrow. Maybe I will luck out and the pop was just cartiledge and the pain is just my imagination (it's not that bad).
