I'm rather eager to try the eccentric exercise, probably just because it's called eccentric.

I went here to see exercises to strengthen external rotators, and a lot of them are things my physical therapist recommended last fall, so now I'm trying to do them on both sides. Except the ones that hurt the new injury too much. Damn it.

And, yes, your summary of calc.tendinitis is pretty much what I've been hearing from doctors and physical therapists. Imagine my joy.
