I got a knee bone bruise a few months ago and I didn't relax my left knee is that bad when you didn't sit down and relax my left knee. I don't know?

See below. The mechanism of injury is important I guess you never sought out any medical attention since you've injured her knee. If you're still having problems such as pain swelling clicking Locking buckling or giving way I would seek an orthopedic surgeon for an evaluation and recommendations. Good luck thank you.
