Knee Question

[Lifter24]

Last night I was doing hack squats and on my last set I got this pain in my knee part way through. Afterwards it was still painful when going up stairs/etc. and is still pretty tender today. Not swollen or red or anything... think I did any serious damage or just take it easy for a few days and it will get better?

Who knows... go see a doc! But generally, if it isn't swollen it's usually not that bad
