I don't think I ever broke my wrist, but many years ago I did something
to it, and peridically it would 'go' again and be unsueably agonising
for a week or two.

I mentioned it to a student doctor, and he stold me that the tissues
repair with scar tissue, which is inflexible, and that rips under stress.

He recommended that I keep the joint moving under low stress when it was
healing.

I practiced sort of rotating 'gay waves' - very limp wristed - the next
time, and it never came back.

Did you make any new friends as a result?
