For what it's worth, I've worked with...nine different PTs over the past six years or so, and I'd say six of them were somewhere between bad and terrible at their jobs and only made my injuries worse. But the other three were good at diagnosing the root issues of injuries and how best to work with and through them, understanding personal limitations and what was too much (or sometimes too little!), gave very personalized care that wasn't just rote nonsense from what they studied, usually had a very hands-on approach as warranted (as opposed to the types who just...stand back and tell you what to do while chattering on and on until your session is over), and ultimately were genuinely helpful. They didn't cure my chronic pains, but they did help make them better and life a bit more tolerable. If you or someone you know tries PT and you're not feeling like you're making any progress over a month or two, just...try out a different one - the level of knowledge, specific skills and abilities, overall approach to your care, and even just the ability to notice what's working and what's not can vary wildly from one to the next.
