I'm doing the 2 day split: DL + bench 1 day and Military press + squat 1 day And I usually squat to where I get low as mid calve but I've been wanting to just dip all the way down and pop back up (let me tell you I'm very green when it comes to squats) so I did just that. Heard a bunch of little pops ( like waking up in the morn and everything pops)no pain nothing. Later that day I go to step up on to the bed of a trailer and I hoist my self up with my right leg then sit down and I feel a radiating pain from the middle of my knee. Nothing that buckles me but enough to alarm me. And I've never felt a pain likenthat before. I feel a slight burning sensation on the inner side of my knee too. I know none of you are doctors and I should go see one. But I would just like to know if anyone by experience could throw out a possibility of what might of happened. If it could be something major.
