In for answers. OP, I think I'm going to give foam-rolling a go. The knee pain is really doing my head in.
I'm a religious squatter (3x a week) and deadlifter. My bad knees are still bad. Lifting heavy helps them, but they still get beaten up. Bursitis in the back of the left knee, and I don't know what in the patella on the right. I've had an ultrasound on the right knee and nothing came up.
