welcome to hcm.
Hats off to ur huge pain threshold. But let me warn u not to be over confident in that regard too. And I really appreciate ur optimistic attitude.
from the history and the description available, it seems that there is a probable ligament tear and U haven't mentioned if ther is any swelling which u can notice.
I would advice you to take a Tab.Diclofenac
SR 75mg twice daily to reduce the inflammation if any and apply a Elastocrepe bandage, 6" around the knee joint and avoid playin for another 1week minimum and I also would recommend you to get a MRI
of the knee if the symptoms persist after 2 days.
