Thanks very much for your reply! Two pieces of information I’ve not heard before that I find extremely useful, are that there are flare ups (so if you have a bad day, not the end of the world, necessarily) and that flexion and extension might help or hurt depending on your specific case. This is reassuring, and also now I know to pay close attention to effects of flexion vs extension movements.
Much appreciated, thanks again! And have a great holiday season.
