Wednesday, last week, was a great practice. But after it, I had some soreness in the right shoulder, way over at the top of the end of the collarbone (I forget the technical name of that bone right now; directly under it is the shoulder bursa and the rotator cuff musculature).
It's still there. Thursday's practice had to be modified, and I haven't practiced since. But with time, as with all injuries, one learns which movements are impinged. It hurts to move the elbow backwards, "behind" my rib cage; that's the major not-to-do movement. Overhead is OK if I'm careful, out to the side is OK, although rotating "forward" when the arm is out to the side, is also a little dicey.
This makes fingers-to-tailbone (my regular Ustrasana approach) hard to do. It also makes vinyasa challenging, in that I need to do them with REALLY close attention (particularly chaturanga alignment; this is, I imagine, the same injury that people who dip below 90 degrees, often get). But on Thursday I did pull vinyasa (with jumps back and through) all the way into the Marichyasanas.
I'll probably begin building practice this week again, but I want to maintain backbends, so the new program might be "Primary til I can't, and then Intermediate to Kapo." Not ideal, but so be it. There might also be some Simha Krama, which is lighter on the vinyasa than proper ashtanga is.
J said yesterday that we should just "wait until she's in the mood." Hahahahaha! That'll be what, 2013????? I love how she can just say stuff like that, with absolutely no regard for how demon-haunted I am about all of this. I freakin' LOVE that.
