I was suffering from diabetic frozen shoulder - one of the most painful things I've ever dealt with, and I've broken my back before, this pain was right up there... it would just simply light me up if I moved ever so slightly in the wrong direction.
Crash - broken shoulder and collarbone.
Fixed, 100% fixed the frozen shoulder. What would have been years of painful PT, where I would essentially be slowly ripping apart the frozen bits and bobs - all over in 1 second. And I had no pain from the broken bones, and both breaks were not in critical locations. No casts or surgery required, not even a sling was needed.
Win win across the board.
