So I have been playing a lot of bball last 2-3 weeks, therefore I have been squatting a lot less. Today, when I was squatting, when I got up to 275 which is pretty heavy and it used to be not that heavy, during 1/4-1/2 squat, under my knee cap i started to feel this pain/discomfort, like my knee might give out, but the pain goes away at the bottom where i would pause, then when i go up the pain comes back at around 1/2 all the way to 1/4. I have never really felt knee pain like this before, like there is some kind of irritation right under top of knee cap at the 1/4-1/2 position.
