here's my injury update:
I feel pretty good. the tightness following the injury is slowly decreasing and mobility increases every day. however, certain movements seem to make me think it could easily pull again, and so, although i've been on the mats a few times this past week or two, i am being very careful. (i am exempt from too much kata which is a nice break).
movements to avoid include: kicking while being supported or pivoting with the bum leg; sparring and/or fast weight transfers; going up on my toes; or any sort of jumping or big breakfalls.
still a bit lame, but much better than before.
