Re: unusual seiza problem - pain in BACK of knee
I have had pain in those tendons before, too. When I first started aikido and was having knee trouble (mainly due to poor from going into seiza), someone recommended kneepads. However, they tended to bunch up behind my knee when I was in seiza, and made the tendons sore. When I stopped using them, the pain went away. I then started having the issue again when I started wearing the hakama -- when I would go down into seiza, sometimes it would bunch up behind the knee and cause pain the back of the knee. Once I started making sure it wasn't bunching under the knee, it wasn't a problem.
