Not sure there is such a thing as a timeline.
I'm over a year in on this broken wrist shit and it's still not right yet. I am assuming that it will never be OK again.
My third trip with broken ribs as well and all seems fine, until I breathe deeply. Worse when I sneeze. Coughing is more controllable.
When I was recovering from hip replacement, they switched me from stabilizing the new hip with weights to building strength in both symmetrically after about three months. That went fine at first, until the pain caused me to cheat some.
My pain caused me to object fiercely to every movement back then.
Forcing through pain is an adulting thing. Kids will have trouble even trying it..
