Knee back pain

hai there, im having pain at my back of my left knee everytime when i wake up from sitting in sukkhasana pose or when i bended my left leg for long time and then straighten my leg. is there any yoga asanas i can do for this.

It’s difficult to tell without checking out your knee in person, but it would at least be a good start to begin stretching the muscles across the back of the knee. Try the stretch below, changing the angle of the stretch every repetition, to access all of the different muscle fibers.
