(of course, the feet are symmetrical in color order).

Of course! I would (do it that way), too.

Yes, I've tried looking for trigger points and massaging them. I don't know whether it's helped. It's blindingly obvious that I do have, by this book's definition, trigger points that need work. That's believable and sane. But whether they are in fact related to my ball-of-foot pain is unclear. My left foot is pretty good, my right is still a mess, and I haven't the foggiest whether they'd be exactly like that *without* what I'd been doing. *sigh* :-)
