THanks for your questions.
I do not intertwine my legs or hook the foot around during this pose – just laying the leg over to the size. My upper leg is probably about perpendicular to my body, so basically a right angle.
My shoulders are comfortable and flat and relaxed on the floor.
I guess this is why I was surprised by my pain in this pose, because I don’t feel like I’m doing any extreme twist when it comes on. Just keeping shoulders to the floor, and laying the leg across the opposite side.
Thanks!
