knee injury

ok, last night I tweaked my ankle, I’ve sprained it a couple times but this wasn’t but I was planning on playing the next day. I could walk around fine before I went to bed, but I this morning I woke up with the most ridicululous pain on the inside of my kneecap, its really painful to bend my knee, and there is a point where I just can’t bend it anymore. It’s really weird because its like it happened while I was asleep. Does anyone have any suggestions to what might be going on?

You injured both but the knee only became noticable the following morning?

I didn’t even realize that my knee was injured when it happened. I saw the trainer and he said it was most likely a very light mcl sprain that tightened up considerably overnight.

Is it inflammed?
