I went to physiotherapy for torticollis, but it was mostly a form of deep tissue massage. Not the usual sort of thing you think when you think massage - it was actually painful and very focused on the injury site. It was basically being repeatedly poked in the neck very hard! I had some kind of internal scarring from an injury years ago that was never treated. I found I had to consciously make myself relax. I dislike being touched, so being touched hard was difficult to endure, and tensing up just made the muscle injury tense up even more. Not sure if that's relevant to the type of physio you're doing for a hip, being bone rather than muscular, though.
I also noted that it is not instantaneous, as it can take several weeks of treatment, and often you can feel more sore, before it begins to correct the problem. The physiotherapist told me that this is common for many kinds of injuries - it'll get worse before it gets better once they start treatment on it. If that happens it's normal - try not to start thinking it's not working or worse, that it's exacerbating your injury or further injuring you.
The neck problems were recurring for me before I had the physio - I'd sleep crooked and it'd come back, or I'd do something exerting like moving furniture and it'd come back, to the point where I was wary of doing anything physical incase it set it off.
Since I had it treated it hasn't recurred though (so far) so it can work.
