My father-in-laws doctors are kinda like this. He’s definitely had real damage in younger years but I think a lot of recent pain is because of a lack of any physical exertion, he’s allergic to stairs and takes the shortest path anywhere.
Spot on about the PT, it was probably the most regular physical exertion he’s done since the last surgery.
My docs are always like you need PT, stretches, and more movement for your upper back/shoulders/heel etc. Also stop doing these X things that bother it. In no way were they going to give me surgery or even pain killers.
