Pain when sitting back on heels

[LitaMS]

Hi,
I am new to these boards. I have yet to see a physiotherapist. I just wondered if anyone had some thoughts on what my knee pain could be caused by. I can do all activities, walking, running, weight lifting. The problem is when I go onto my knees and I sit back on my heels, my knees hurt like crazy. I find it impossible to put my weight on my heels. Example if you were to do the yoga move child's pose. Putting my weight on my feet in this position hurts like crazy. Any ideas out there? Thanks.

So it's when your knee is fully flexed? Could be a number of things from an articular cartilage injury, to a plica, to patellofemoral pain.
Avoid doing that move and if that's not possible, see a physio or similar!

Thanks Heidi,
I know I need to see my a physiotherapist. I can fully flex my leg when doing a quad stretch but I can feel it a little. It is when I put my weight on it, I can't fully put my weight on my feet in that position. Is it possible if I see my physio therapist that my knee will feel normal again? It is very discouraging since I am an active person. Thanks for your response.

Also Heidi, the pain has been around almost a year, it has not gotten worse. I just work around it, sadly it has never gone away. Thanks again for your response.

Have you ever determined what this is from? I have the exact same thing. I discovered this when I started doing P90X (Child's pose). I am thinking it could be the popliteus behind the knee. Sometimes i can feel the pain shoot to me foot.
