@Celle - Honestly, I SWEAR I have not been exercising that much. I am doing some gentle restorative yoga occasionally (no kneeling), but I have even slacked off of the PT in recent weeks. Being back at work, I can't fit in more than one session a week. Since this decision was made about the MUA, I have not done PT. I am just going to let it ride for the moment.
Honestly, I have wondered if it's "my fault" that my right side hasn't recovered ROM that well. It makes me feel like I didn't do enough - didn't try hard enough. But, in PT, I would loosen it up on the bike, or my therapist would massage and bend it, so we could get to maybe 108 (with both of us trying really hard), and then by two hours later, any ROM achieved in therapy would be gone. The improvements have been very small increments and don't seem to last.
It's especially interesting to be in this position after having a bilateral. If I could not directly make the comparison between right and left, I might think what is happening (or, rather, not happening) on the right is normal. The left has done so much better - still not close to the longed-for 130, but some hope I may yet get there.
It's coming at a decent time, at least. My office is moving the week it's scheduled, and I will be able to stay home for the entire week after having MUA. That is going to give me the best chance to ice and rest and recover fully. I appreciate your advice about going easy on the PT afterward. I would also be interested to hear more specifics about which gentle exercises might be advisable.
