Just another anecdote to support @THowe
I have two very ‘loosely’ put together shoulders that I can dislocated pretty easily. Even with more severe dislocations a large portion of the pain goes away once the joint is back together
Not to say a traumatic dislocation can’t be an extremely severe injury, but I’ve dislocated shoulders in crashes 3x and was unable to ride afterwards once…so totally possible he dislocated it
